Abstract:
A fuel cell includes a fuel cell stacked body in which a plurality of fuel cells are stacked in a first direction, a pair of end plates which sandwiches the fuel cell stacked body in the first direction, and a load measurement unit that is disposed between at least one of the pair of end plates and the fuel cell stacked body, and detects an electrode load, which acts on a power generation surface of the fuel cells, in the first direction. The load measurement unit includes a first conductive material, second conducive materials between which the first conductive material is interposed in the first direction, and which include a contact portion that is in contact with the first conductive material, and a detection unit that detects a voltage drop between the second conductive materials, which face each other in the first direction, with the first conductive material interposed therebetween.
