Title:
FUEL CELL STACKS WITH BENT PERIMETER FLOW FIELD PLATES
Document Type and Number:
WIPO Patent Application WO/2017/216621
Kind Code:
A3
Abstract:
By introducing appropriate bends at the perimeters in the flow field plates used in solid polymer electrolyte fuel cell stacks, certain improvements can be obtained. Bends introduced at the outer perimeter of either or both of the oxidant and fuel flow field plates can serve to mechanically protect and electrically isolate the cell edges from each other and from external support structures. Bends introduced at the perimeters of reactant ports in the flow field plates can improve the flow of reactants through the manifolds created from the stacking of the ports in the stack.
