摘要： A cooling plate in which flow channels are modified to reduce temperature differences between portions of the cooling plate and provide for more uniform heat distribution within a heat generator. The flow channels of the cooling plate are formed such that a central portion of the flow channels has a greater volume than the end portions near an inlet and an outlet so that the amount of cooling water that is contained in the central portion at any one time is larger than either of the end portions near the inlet and the outlet. Likelihood of thermal deformation of the cooling plate due to thermal stress is decreased, and stability of performance of the fuel cell is increased.

摘要： A heat exchanger that can mechanically automatically control a level of cooling water according to heat generation of the fuel cell. The heat exchanger includes a housing having a cooling water inlet and an outlet connected to a fuel cell stack, a moving plate which moves reciprocally in the housing and discharges cooling water filled in the housing to the stack when it moves in a one direction and when it receives a steam pressure from the stack it moves in an opposite direction, and an elastic member that applies a force to the moving plate in the one direction. The heat exchanger can automatically maintain the level of cooling water despite a difference in heat generated between a full and a partial load operation of the fuel cell obviating complicated electronics such as a thermo-sensor, a valve, or a controller. Also, under a partial load, the exposure of flow channels to superheated steam is avoided, thereby extending the lifetime of the fuel cell.
