Polymer electrolyte membrane fuel cells are gaining great attention as a source of power generation for automotive applications. One key requirement for automotive applications is that the fuel cell must be tolerant of frequent start-stop cycling. A new decay mechanism related to local hydrogen starvation, which may be present during start-stop procedures, has been discovered. [...]

Polymer electrolyte membrane fuel cell is the most appropriate power source candidate for the next-generation electric vehicle and small-scale stationary power. In recent years, durability has been one of the most important issues to be solved before the commercialization of PEMFCs. PEMFC performance loss under steady-state and cycling conditions has been attributed to the significant [...]
