Abstract
A fuel cell system that generates electric power by supplying anode gas and cathode gas to a fuel cell includes a control valve adapted to control the pressure of the anode gas to be supplied to the fuel cell; a buffer unit adapted to store the anode-off gas to be discharged from the fuel cell; a pulsation operation unit adapted to control the control valve in order to periodically increase and decrease the pressure of the anode gas at a specific width of the pulsation; and a pulsation width correcting unit adapted to correct the width of the pulsation on the basis of the temperature of the buffer unit.
Claims1
A fuel cell system that generates electric power by supplying anode gas and cathode gas to a fuel cell, comprising:
- a control valve adapted to control a pressure of the anode gas to be supplied to the fuel cell;
- a buffer unit adapted to store an anode-off gas to be discharged from the fuel cell;
- and
- a controller programmed to:
- control the control valve in order to periodically increase and decrease the pressure of the anode gas at a specific width of a pulsation;
- and
- correct the width of the pulsation based on a temperature of an upstream buffer volume comprising an anode gas flow passage from the control valve to the fuel cell.
