The study&#8217;s graphical abstract was also selected to be featured as the Supplementary Cover Art for the issue.<\/p>\n\n\n\n<p>\u3000This research investigated the comprehensive durability of mesoporous carbon-supported platinum catalysts (Pt\/MPC), a highly promising material for polymer electrolyte fuel cells (PEFCs) used in fuel cell vehicles and stationary power systems. The study focused on performance under realistic operating conditions, including startup and shutdown cycles. The findings revealed that MPC catalysts experience more significant performance degradation compared to conventional Ketjen Black and graphited Vulcan catalysts. By conducting a detailed analysis of the amount and timing of CO<sub>2<\/sub> gas emissions, we clarified the specific degradation mechanism. Furthermore, we demonstrated that this degradation can be effectively mitigated by precisely controlling the upper potential limitation through micro-power generation during operation.<\/p>\n\n\n\n<p>\u3000This research was conducted as a joint project with N.E. CHEMCAT Corporation, supported by the New Energy and Industrial Technology Development Organization (NEDO). The insights gained by the Satoshi Aoki (an employee of N.E. CHEMCAT and a PhD student in Yamanashi university&#8217;s doctoral program for working professionals), are expected to provide crucial guidance for the design of next generation electrocatalysts and fuel cell systems with extended lifespans.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"771\" height=\"1024\" src=\"https:\/\/fc-nano.yamanashi.ac.jp\/english\/wp-nano_e\/wp-content\/uploads\/2026\/04\/\u30ab\u30d0\u30fc\u30a4\u30e9\u30b9\u30c8_border-771x1024.jpg\" alt=\"\" class=\"wp-image-911\" style=\"aspect-ratio:0.7529411764705882;width:442px;height:auto\" srcset=\"https:\/\/fc-nano.yamanashi.ac.jp\/english\/wp-nano_e\/wp-content\/uploads\/2026\/04\/\u30ab\u30d0\u30fc\u30a4\u30e9\u30b9\u30c8_border-771x1024.jpg 771w, https:\/\/fc-nano.yamanashi.ac.jp\/english\/wp-nano_e\/wp-content\/uploads\/2026\/04\/\u30ab\u30d0\u30fc\u30a4\u30e9\u30b9\u30c8_border-452x600.jpg 452w, https:\/\/fc-nano.yamanashi.ac.jp\/english\/wp-nano_e\/wp-content\/uploads\/2026\/04\/\u30ab\u30d0\u30fc\u30a4\u30e9\u30b9\u30c8_border-768x1020.jpg 768w, https:\/\/fc-nano.yamanashi.ac.jp\/english\/wp-nano_e\/wp-content\/uploads\/2026\/04\/\u30ab\u30d0\u30fc\u30a4\u30e9\u30b9\u30c8_border.jpg 965w\" sizes=\"auto, (max-width: 771px) 100vw, 771px\" \/><\/figure>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>\u3000A paper by Prof. Makoto Uchida and his colleagues at the Hydrogen and Fuel Cell Nanomaterials Center has been \u201cDegradation Mechanism and Mitigation Strategy of Mesoporous Carbon-Supported Pt Catalysts during Realistic Startup and Air Confinement Shutdown in Polymer Electrolyte Fuel Cells\u201d published in ACS Applied Energy Materials, a journal of the American Chemical Society.
