FLOW FIELD PLATE FOR AN ELECTROCHEMICAL FUEL CELL
Abstract:
A flow field plate for an air-cooled fuel cell comprising: an anode flow field comprising a serpentine anode flow channel with a plurality of passes, wherein each pass is separated by an anode landing and each pass is fluidly connected to an adjacent pass by a recess formed in the anode landing; and an opposing cathode flow field comprising a plurality of cathode flow channels, wherein each cathode flow channel is separated by a cathode landing; wherein: the anode landing forms the cathode flow field channels; and a depth of the recess in the anode landing is less than a depth of the cathode flow channels.
