CONTROL DEVICE OF FUEL CELL, FUEL CELL SYSTEM AND CONTROL METHOD OF FUEL CELL

摘要

A fuel cell has an electrolyte membrane of 5 to 10 μm in thickness. A control device for this fuel cell comprises: a controller configured to control an amount of power generation by the fuel cell according to a required amount of electric power; and a power generation reducer configured to reduce the amount of power generation by the fuel cell at a humidity of an electrolyte membrane of 95 to 98% RH to be lower than the amount of power generation at the humidity of the electrolyte membrane of lower than 95% RH.

1. A control device for a fuel cell, comprising:
a controller configured to control an amount of power generation by the fuel cell according to a required amount of electric power; a power generation reducer configured to reduce the amount of power generation by the fuel cell at a humidity of an electrolyte membrane, which is included in the fuel cell and is formed to have a thickness of 5 to 10 μm, of 95 to 98% RH to be lower than the amount of power generation at the humidity of the electrolyte membrane of lower than 95% RH, and a cracking detector configured to detect cracking in a catalyst layer of the fuel cell, wherein in response to detection of cracking in the catalyst layer, the controller controls the fuel cell to make power generation according to the required amount of electric power, regardless of the humidity of the electrolyte membrane.
