Abstract:
Provided are: a fuel battery compression mechanism capable of suppressing detachment of a biasing part which biases a cell group; and a fuel battery equipped with the same. This fuel battery compression mechanism is equipped with: plates provided at one end portion 11 of a stack case 10 for accommodating a cell group 20 formed by arraying a plurality of fuel battery cells; and biasing parts (first biasing part 50, second biasing part 80) that are provided to the plates and that bias the cell group 20 so as to compress the cell group in the arraying direction. The plates include an end plate 70 and a pressure plate 30 disposed between the end plate 70 and the cell group 20. The fuel battery compression mechanism is equipped with a covering member (first film 60, second film 90) that is provided to, among the end plate 70 and the pressure plate 30, at least one of the plates, and that is provided so as to cover a portion of said plate and the corresponding one of the biasing parts provided to the plate.
