Abstract An advanced cathode design can improve the power performance and durability of proton exchange membrane fuel cells (PEMFCs), thus reducing stack cost cell vehicles (FCVs). Recent studies on highly active Pt alloy catalysts, short-side-chain polyfluorinated sulfonic acid (PFSA) ionomer 3D-ordered electrodes have imparted PEMFCs with boosted density. To achieve compacted target 6 kW/L or...

Subzero cold-starts are one of the last remaining challenges to commercialization automotive fuel cells. The ultimate cold-start target is exothermically self-start a cell stack from ?20 °C attain 50% rated power within 30 s, expending only 5 MJ start-up/shutdown power—currently unattainable with today’s materials, thus exacerbating performance gap future advanced materials. There exists discon...

This paper deals with the performance analysis of a proton exchange membrane fuel cell in automotive applications and especially for start/stop phases. Start-Stop cycles are one main sources degradation systems, embedded applications, among other dynamic conditions as idling, load cycling or high power. In this study, polarization curves electrochemical impedance spectra used to analyze mechani...

In today's automotive business environment, responsibility for module and sub-system design and development is increasingly driven into the supply chain. Simultaneously, the pressure to reduce product cost is maintained if not increased. The engineering organizations of the higher tier suppliers are saddled with the task of managing a product development portfolio ranging from largely mature pr...
