Oita College and Hitachi High-Tech Give a Joint Presentation on the Employ of AI Know-how to Delay the Lifespan of Polymer Electrolyte Gas Cells
TOKYO, Oct 11, 2024 – (JCN Newswire) – National College Company OITA UNIVERSITY (“Oita University”) and Hitachi High-Tech Company (“Hitachi High-Tech”) recently announced that we have began conducting compare (“this research”) into predicting and extendingthe existence of electrocatalysts earlier in polymer electrolyte gasoline cells (PEFC), the exercise of Hitachi High-Tech’s technology that makes exercise of AI to compose image analysis. We are in a position to be giving a joint presentation on the contents of this compare at The Chemical Society of Japan Autumn Tournament 14th CSJ Chemistry Festa 2024, which may perhaps perchance well additionally be held at Tower Hall, Funabori (Tokyo) from October 22 to 25, 2024.
Kinumoto Laboratory at the Faculty of Science and Know-how of Oita College is targeted on compare initiatives the exercise of the Identical Region Field Emission-Scanning Electron Microscope (IL-FE-SEM)*1 of Oita college’s proprietary technology to resolve out the degradation mechanism of PEFC electrocatalysts and create tough PEFC.This compare is phase of the Green Applied sciences for Excellence (GteX)*2 challenge of the Japan Science and Know-how Company (JST).
Hitachi High-Tech develops, manufactures, and sells electron microscopes, so has a wealth of skills in the analysis of observation photos, also solves complications faced by customers the exercise of informatics applied sciences, Offers Informatics (MI) and Course of Informatics (PI)*3. Hitachi High-Tech has drawn on these strengths and combined them with AI and SEM image analysis applied sciences to produce make stronger for Oita College’s PEFC compare and explain.
Including with this compare, Oita College and Hitachi High-Tech goal to continue working to mosey up efforts to create longer-lasting PEFC going ahead and contribute to solving social components equivalent to by achieving carbon neutrality and a decarbonized society.
Background
PEFC are a model of gasoline cell that exercise polymer affords as the electrolyte*4 to generate electricity (vitality) by inflicting chemical reactions between hydrogen and oxygen at two electrodes. Gas cells of all kinds are more and more earlier as a model of sustainable vitality that will perhaps perhaps chop CO2 emissions and, among these, PEFC are also earlier in day after day purposes equivalent to vehicle and household energy sources. Because the achievement of carbon neutrality becomes is named a key squawk coping with society, it’s predicted that PEFC will became more and more necessary. To that kill, on the other hand, PEFC of their recent notify must be elevated sturdiness, with elevated output, and lower in observe. This compare targets to shed gentle on the mechanism in the merit of the degradation of electrocatalysts, which is the utmost most primary squawk in prolonging PEFC existence, by the exercise of AI technology to examine FE-SEM observation photos and own more efficient analysis in accordance to quantitative data imaginable.
Overview of this Analysis
This compare earlier Oita College’s IL-FE-SEM technology and Hitachi High-Tech’s AI- powered image analysistechnology to survey electrocatalyst sturdiness and ground degradation thru accelerated degradation checks in which a pulse voltage is over and over applied to the PEFC electrocatalysts.*5
In say to resolve out the deterioration mechanism, in which there may perhaps be a reduction in the electrochemical ground condominium (ECSA)*6 of the electrocatalytic platinum particles, Oita College is the exercise of IL-FE-SEM technology to visually inspectand analyze the platinum particles in observation photos. Then all as soon as more, even though it’s imaginable to make exercise of IL-FE-SEM technology to manufacture a orderly quantity of observation photos, this has its complications in that there may perhaps be an infinite workload focused on analyzing the full observation photos attributable to there being hundreds of platinum particles recent in every particular particular person image. To resolve this squawk, Hitachi High-Tech equipped AI-pushed image analysis technology to streamline the task of image analysis. Particularly, AI image analysis became as soon as earlier to detect*7 platinum particles recent in every test. After the particles had been detected in the photos that had been taken, adjustments in the placement of the particles (their disappearance, aggregation, or formation) may perhaps perchance well be tracked and the particle depend robotically particular.
Going ahead, the researchers will continue to work to give a lift to particle detection accuracy and own traits in determining the degradation mechanism of more efficient PEFC, as every Oita College and Hitachi High Tech will push ahead and continue to work collectively to create lengthy-lasting PEFC. They’re going to also contribute to the cultivation ofdata scientists with a grounding in chemistry by working in conjunction with the college students of Oita College on pushing this analysis ahead.
This compare is being completed thru technical collaboration with Hitachi Co., Ltd. (“Hitachi”), and the presentation at CSJ Chemistry Festa 2024 is deliberate to be completed jointly by Oita College, Hitachi High-Tech, and Hitachi.

– The date and time of the presentation on this compare: Wednesday, October 23, 1:30 PM to a few:30 PM within the Festa thought, pupil poster presentations*8.
– Presentation topic: “Evaluation of Degradation of Pt/C Electrocatalysts for PEFC the exercise of Identical Region FE-SEM Commentary and AI Image Evaluation”
(1) Identical Region Field Emission-Scanning Electron Microscope (IL-FE-SEM): It refers back to the observation of a tough and rapid-level the exercise of FE-SEM and is a technology independently developed by Oita College. Observing a tough and rapid-level may perhaps perchance well additionally be earlier effectively in compare tracking and determining adjustments in physical topic.
(2) Green Applied sciences for Excellence (GteX): A challenge by JST for supporting R&D and personnel explain at universities, National Analysis and Vogue Agencies and identical institutions with the goal of continually establishing new applied sciences focused in the direction of achieving GX (green transformation).
(3) Offers Informatics (MI) and Course of Informatics (PI): Initiatives to own affords explain more efficient by the exercise of informatics tactics that leverage statistical analysis and masses of such methodologies. MI is mainly earlier to predict area topic properties or for kind capabilities, whereas PI is mainly earlier to streamline the production task.
(4) Electrolytes: A substance earlier to transfer ions between electrodes and facilitate an electrochemical response.
(5) Sturdiness sorting out the exercise of an accelerated degradation test (ADT). ADT evaluates gasoline cell sturdiness by making exercise of a fixed capacity pulse to a sample. FE-SEM became as soon as earlier to image the same location on the catalyst ground to survey the degradation in the cathode catalyst ground occurring over repeated checks.
(6) Electrochemical ground condominium: It refers back to the ground condominium over which the response occurs, and it serves as a in point of fact most primary metric when evaluating the performanceof catalysts and electrode affords. The elevated the electrochemical ground condominium, the elevated the electrochemical response effectivity.
(7) Detected particles the exercise of semantic segmentation. Semantic segmentation assigns labels to every and each pixel in a image, enabling a true stage of detection even across huge image areas.
(8) Student poster presentations: A pupil poster session will be held with the goal of encouraging dialogue between college students and enterprise, academia, and authorities representatives.
