Systematic Assay of the Influence of Current Ripples on Polymer Electrolyte Membrane(s) in Low-Temperature Fuel Cells
The influence of current ripples on long term degradation of PEM fuel cells was systematically investigated. Test stacks were exposed to synthetic current ripples of various frequencies and extraordinary amplitudes for longer time intervals. In summary it can be stated that hints to an impact of current ripples on long term degradation of stacks could not be identified. In consequence, demands to inverter manufacturers to care for strict limitation of ripples in fuel cell circuits could be re-assessed, thus sparing cost and losses of filters.
