FUEL CELL STACK, AND METHOD OF DETERMINING MAINTENANCE TIME OF FUEL CELL STACK

摘要

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.

1. A fuel cell stack, comprising:
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 from both sides 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, wherein the load measurement unit includes,
a first conductive material,second conducive materials which sandwich the first conductive material in the first direction, and which include a contact portion that is in contact with the first conductive material, anda 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.
