A fuel cell including a stack of electrochemical cells, a pair of end plates located at each end of the stack of cells, and a cooling system for cooling the cells. The cooling system includes a coolant fluid circulating in closed loop through the stack and in the end plates, such that the coolant fluid exchanges heat with the end plates.

Compact fuel cell

The invention relates to a method for protecting a set of electrochemical cells incorporated into a fuel cell stack from corrosion during an operation for shutting down the fuel cell stack, which method comprises steps of:

Preventing corrosion in a fuel cell

A flat fuel cell including: at least two unit cells, a casing provided with supports for each of said unit cells, said supports offering a bearing surface to a periphery of the unit cells, a sealing member interposed between the periphery of each unit cell and the surface of an associated support, and a cover forming a compression element coming into abutment on the periphery of each unit cell opposite the sealing member and cooperating directly with the associated support in order to provide compression of the sealing member.
