Abstract
A fuel cell system is provided with a fuel cell (12) having a fuel electrode (19) supplied with fuel gas and an air electrode (16) supplied with oxidizer gas, a carbon dioxide separator (15, 52, 71) separating carbon dioxide from anode exhaust gas (25) expelled from the fuel electrode of the fuel cell, and a fuel vaporizer (13, 58) producing fuel gas by injecting fuel into anode exhaust gas, whose carbon dioxide is separated in the carbon dioxide separator and which is expelled from the carbon dioxide separator. Fuel gas produced in the fuel vaporizer is supplied to the fuel electrode of the fuel cell.
Claims14
A fuel cell system comprising:
- a fuel cell having a fuel electrode supplied with fuel gas and an air electrode supplied with oxidizer gas;
- a carbon dioxide separator separating carbon dioxide from anode exhaust gas expelled from the fuel electrode of the fuel cell;
- and
- a fuel vaporizer producing fuel gas by injecting fuel into the anode exhaust gas, whose carbon dioxide is separated in the carbon dioxide separator and which is expelled therefrom, with the fuel gas produced by the fuel vaporizer being supplied to the fuel electrode of the fuel cell.
A fuel cell system comprising:
- a fuel cell having a fuel electrode supplied with fuel gas and an air electrode supplied with oxidizer gas;
- carbon dioxide separating means for separating carbon dioxide from anode exhaust gas expelled from the fuel electrode of the fuel cell;
- and
- fuel injecting means for injecting fuel into the anode exhaust gas, whose carbon dioxide is separated in the carbon dioxide separating means and which is expelled therefrom, to produce gas, with the fuel gas produced by the fuel injecting means being supplied to the fuel electrode of the fuel cell.
A method of citing gas in a fuel cell system provided with a fuel cell having a fuel electrode supplied with fuel gas and an air electrode supplied with oxidizer gas, the method comprising;
- separating carbon dioxide from anode exhaust gas expelled from fuel electrode of a fuel cell;
- producing fuel gas by injecting fuel into the anode exhaust gas, whose carbon dioxide is separated and which is expelled;
- and
- supplying the fuel gas into the fuel electrode of the fuel cell.
