Internally humidified, edge-air-cooled PEFC stacks are promising for portable systems in terms of specific power and specific cost. However, their main drawbacks are thermal power limitations due to limited heat removal from inside the stack. The aim

This paper presents a method for collecting ac impedance data from a commercial PEFC power system at operational loads. The PEM fuel cell stack in the power system, including 47 MEAs, was operated using room air and pure hydrogen (>99.99%). For a sta

The impedance characteristics of various Ni-Cd cells were measured at different times during accelerated charge/discharge trials to identify characteristics indicative of cell lifetime and cycle history. The tests were performed as part of an attempt
