Abstract
A fuel cell arrangement including a plurality of fuel cells, each fuel cell including an electrolyte membrane disposed between an anode and a cathode, first and second flow field plates adjacent the anode and cathode, respectively; a fuel cell health management (FCHM) device; a plurality of plate members interposed between each of the fuel cells and being made of an electrically conductive metallic material and disposed between the first and second flow field plates of adjacent fuel cells to connect the fuel cells in series, and having an electrically conductive tab. The tab of each of the plate members being electrically connected to the FCHM to conduct current provided by the FCHM to provide a substantially uniform voltage over each electrically of the plate members to rejuvenate each fuel cell, to monitor each fuel cell, and to control each fuel cell, and having a heat sink for dissipating heat.
