ABSTRACT:
An end unit for a fuel cell stack having a plurality of fuel cell stacked in a first direction, the end unit for stacking in the first direction adjacent an end fuel cell in the fuel cell stack. The end unit separates a current collection post from the end cell of the fuel cell stack and comprises a first wall being adjacent the end cell when the end unit is stacked in the first direction in the fuel cell stack, a second wall opposing the first wall and adjacent the current collection post when the end unit is stacked in the first direction in the stack, a first side wall connecting the first and second walls, a second side wall transverse to the first side wall and connecting the first and second walls, a third side wall opposing the first side wall and connecting the first and second walls, a fourth side wall opposing the second side wall and connecting the first and second walls, with the first and second walls and the first, second, third and fourth side walls forming an enclosure, and a plurality of electrically conductive posts disposed within the enclosure and extending between the first and second walls for providing a structure which restricts electrical current flow from the first fuel cell stack to the current collection post when the end unit is stacked in the first direction in the fuel cell stack.
