Abstract
A vehicular mountable fuel cell system constituted by combusting means 1 for combusting off gas from a fuel cell 4 supplied with reformed gas from a reformer 3 and a turbine compressor 2 for supplying air to the fuel cell 4 by compressing air at a compressor unit 22 by operating combustion energy of the combusting means 1 to a turbine unit 21 to thereby reduce power of a motor for driving to rotate the turbine compressor by recovering power by effectively using waste gas.
Claims10
A fuel cell system comprising:
- a combustor connected for combusting an off gas from a fuel cell supplied with a reformed gas from a reformer;
- a turbine compressor connected to the fuel cell so as to supply air to the fuel cell by compressing air, the turbine compressor including a compressor unit utilizing combustion energy of the combustor;
- a flow rate sensor for detecting a flow rate of the air supplied from the compressor unit to the fuel cell;
- a flow rate sensor for detecting a flow rate of the reformed gas supplied from the reformer to the fuel cell;
- calculating means for calculating a flow rate of oxygen and a flow rate of hydrogen to be supplied from the fuel cell to the combustor based on a detected amount of the air and a detected amount of the reformed gas;
- and
- flow rate controlling means for controlling the flow rate of oxygen and the flow rate of hydrogen to be supplied to the combustor in accordance with a control signal from the calculating means.
