PROBLEM TO BE SOLVED: To save the space for a warming-up device of a fuel cell. SOLUTION: This fuel cell stack 26 is provided with a support member 411 in a stack direction of fuel cell cells 2 and separators 6, connecting terminals 413 are supported toward the separators 6, the connecting terminals 413 connected to the separators 6 adjacent to each other are connected by a variable resistor element 42, and the support member 411 is moved back and forth toward the fuel cell stack 26 along a guide member 412 by a solenoid 414, to form a short-circuiting means 40. The support member 411 is moved by driving the solenoid 414, and the connecting terminals 413 are connected to the separators 6, whereby a short-circuiting circuit for short-circuiting a cell 2 of the fuel cell is formed, and the warming-up is performed by the heat generation by internal resistance and the reaction heat in heat generation. |
