FUEL CELL STACK WITH MULTILAYER TYPE COLLECTOR PLATE

摘要

A fuel cell stack is provided which manually increases the temperature of cells arranged in the vicinity of an end plate of the stack to improve starting performance of a fuel cell vehicle at temperatures below zero and driving performance thereof at low temperatures. The fuel cell stack realizes rapid thawing and heating functions in response to freezing of end cells when a vehicle is started at temperatures below zero, using a multilayer current collector having at least one thin collector plate which is structurally and sensitively expandable or contractible based on temperature changes.
