Abstract
A fuel cell stack (2) of a fuel cell power plant (1) generates electric power using a fuel gas such as hydrogen supplied from a fuel gas supply device (3, 5, 5a), and an oxidant gas such as air supplied from an oxidant gas supply system (4). The fuel cell stack (2), fuel gas supply device (3, 5, 5a) and oxidant gas supply system (4) are housed in a casing (6). The casing (6) is provided with a ventilation fan (7). The concentration increase of the fuel gas in the casing (6) due to leaks is appropriately suppressed by the controller (10) controlling the operation of the fan (7) based on the power generation load of the fuel cell stack (2).
Claims10
A fuel cell power plant comprising:
- a fuel cell stack comprising a laminate of fuel cells each of which comprises an anode a cathode and an electrolyte to generate power by an electrochemical reaction between a fuel gas supplied to the anode and an oxidant gas supplied to the cathode, via the electrolyte;
- a fuel gas supply device which supplies fuel gas to the anode;
- an oxidant gas supply device which supplies oxidant gas to the cathode;
- a casing which, among the fuel cell stack, the fuel gas supply device and the oxidant gas supply system, houses at least the fuel cell stack;
- a ventilator which ventilates the inside of the casing;
- and
- a controller programmed to control operation of the ventilator according to a power generation load of the fuel cell stack.
