Fuel cell system

Japanese Patent JP6237067

B2

PROBLEM TO BE SOLVED: To accelerate warming-up of a fuel cell.SOLUTION: A fuel cell system according to the invention, which generates power by supplying anode gas and cathode gas to a fuel cell and causes a vehicle to run with the generated power, comprises: warm-up-period accessory control means that gradually increases the power consumption of an accessory during the warm-up period of a fuel cell, thereby exerting control such that the consumption power has a constant value; stationary-period lower limit power calculating means (S1) that calculates stationary-period lower limit power that is the lower limit value of the output of the fuel cell during a stationary period after control is exerted such that the consumption power of the accessory has a constant value during transition in which the power consumption of the accessory is gradually increased; and transition-period current voltage characteristic estimating means (S3) that estimates the current voltage characteristics of the fuel cell according to output voltage when the output current of the fuel cell is decreased with a predetermined swing width by increasing the output current of the fuel cell is increased after the output of the fuel cell reaches the constant-period lower limit power.
