摘要： A fuel cell stack is formed by stacking unit cells and each unit cell is formed by sandwiching a membrane electrode assembly between a pair of separators having depression parts and protrusion parts. A cooling liquid flow space is formed between the unit cells, and a displacement absorption member which absorbs displacement between the unit cells is disposed in the flow space. The displacement absorption member includes a spring function part having a free end and a fixed end, and an intrusion prevention means which prevents the free end of the spring function part from intruding into the depression part. A displacement absorption function between the unit cells is well maintained, while size reduction of the fuel cell stack is achieved.

摘要： Methods are disclosed for starting up a fuel cell system from starting temperatures below 0° C. The methods apply to systems comprising a solid polymer electrolyte fuel cell stack whose cathodes comprise an oxygen reduction reaction (ORR) catalyst and whose anodes comprise both a hydrogen oxidation reaction (HOR) catalyst and an oxidation evolution reaction (OER) catalyst. In the methods, from the beginning of starting up until the fuel cell temperature reaches 0° C., the fuel cell stack current is kept sufficiently low such that the current density drawn does not exceed the stack's capability for the oxidation evolution and the oxygen reduction reactions to occur at the anode and cathode respectively (i.e. current density drawn is less than the stack's maximum OER/ORR current density).

摘要： A fuel cell stack has a stacked plurality of single cells. Each of the single cells has a membrane electrode assembly, and a pair of separators sandwiching the membrane electrode assembly therebetween. A cooling fluid channel where a cooling fluid flows is formed between adjacent single cells. The fuel cell stack further comprises a displacement absorbing member disposed in the cooling fluid channel to absorb a displacement between the single cells. The displacement absorbing member comprises a channel flow resistance reduction structure that reduces a channel flow resistance of the cooling fluid channel against the cooling fluid.

摘要： Improved methods are disclosed for shutting down and storing a fuel cell system, particularly for below freezing temperature conditions. The methods comprise stopping power production from the fuel cell stack, monitoring its temperature, and repeatedly performing a predetermined warming operation if the stack temperature falls to a normal threshold temperature. In the improved methods, either an initial threshold temperature and/or an initial warming operation are used that differ from the respective normal threshold temperature and the predetermined warming operation.

摘要： A deformation absorption member for a fuel-cell-stack disposed between an anode side separator and a cathode side separator. The deformation absorption member includes a thin-board-like base material, and a plurality of raised pieces in which extension portions extended from proximal ends are arranged in a grid pattern. Each raised piece of the plurality of raised pieces is formed in a non-rectangular shape in which the width of the extension portion is shorter than the width of the proximal end, and plurality of raised pieces are configured so that the directions of the extension portions of mutually adjacent raised pieces are alternately arranged, and positions of the proximal ends of the mutually adjacent raised pieces are arranged in at least overlapping positions.
