PROBLEM TO BE SOLVED: To provide a hydrogen peroxide concentration detection sensor capable of satisfactory and precisely detecting hydrogen peroxide concentration at a particularly minute position.SOLUTION: A hydrogen peroxide concentration detection sensor 60 for fuel cell has a plate of metal catalyst 64 formed on the surface of an ion exchange membrane 62. A first isolation coating 66a and a second isolation coating 66b are formed being interposed by the metal catalyst 64 with one end part 64a and the other end part 64b of the metal catalyst 64 exposed to the outside. On the one end part 64a of the metal catalyst 64, a coating layer 68 containing an ion exchange component is formed.SELECTED DRAWING: Figure 4 |
