Title:
Fuel cell monitoring instrument
Document Type and Number:
Japanese Patent JP6115261
Kind Code:
B2
Abstract:
In a fuel cell monitoring device, a gas-diffusion resistance calculation section calculates a gas-diffusion resistance Rtotal indicating a difficulty of diffusing reaction gas to a catalyst layer in a fuel cell based on a gas reaction resistance Rct calculated by a resistance calculation section. A second diffusion resistance calculation section calculates a second diffusion resistance Rdry varying depending on a dried-up in the fuel cell based on a proton transfer resistance Rmem calculated by the resistance calculation section. A first diffusion resistance calculation section calculates a first diffusion resistance Rwet varying depending on a flooding in the fuel cell by subtracting the second diffusion resistance Rdry from the gas-diffusion resistance Rtotal. A water content calculation section calculates a water content of the fuel cell based on the first diffusion resistance. A recovery control section adjusts the water content in the fuel cell based on the calculated water content.
