PROBLEM TO BE SOLVED: To provide a fuel cell stack capable of achieving a high output voltage of a stack even when the number of stacked cells of the stack is reduced, by using a separating plate in which two or more reaction areas are connected in an insulated manner.SOLUTION: A fuel cell stack according to the present invention employs: a separating plate with a novel structure, in which two or more reaction areas are connected in an insulated manner by means of an insulating material as a medium to increase a voltage capable of being generated in the stack and maintain a current at a low level; and a stack module which is formed by sequentially stacking a gas diffusion layer, an electrode membrane assembly, and the like on each reaction area and has two or more reaction parts. The reaction parts are connected in series to configure one stack module. Thereby, the number of stacked cells of the stack can be reduced to reduce man-hours and cost for manufacture, the productivity and the vehicle mountability of the stack can be improved, and an improvement in efficiency of drive components due to a high output voltage of the stack can be achieved. |
