摘要： The present invention provides a method of operating a fuel cell system and a fuel cell system that can adjust the operating pressure of the fuel cell system to maximize efficiency. This present invention recognizes that under certain operating conditions appropriately matched operating pressures enable a substantially more efficient system operation. The method of the present invention and the fuel cell system of the present invention incorporate the recognition that a higher system efficiency can be achieved when the operating pressure produced by the air compressor is matched to the prevailing operating temperature of the fuel cell system.

摘要： A fuel cell system that employs a recuperative heat exchanger to provide additional cooling for the compressed charge air applied to the cathodes of the fuel cells in the fuel cell stack. The cathode exhaust gas is applied to the recuperative heat exchanger so that the cathode exhaust gas cools the charge air heated by the compressed air. A cathode exhaust gas expander is provided in combination with the recuperative heat exchanger that uses the energy in the heated cathode exhaust gas to power the charge air compressor. An anode exhaust gas combustor can be provided that burns residual hydrogen in the anode exhaust gas to further heat the cathode exhaust gas before it is applied to the expander.

摘要： A method of regulating a relative humidity of a gas supplied to a cathode side of a fuel cell stack includes controlling a flow of feedback gas from the cathode side to a compressor to adjust the relative humidity of the gas. Injected water into the compressor is vaporized in the compressor to further adjust the relative humidity of the gas. The gas is discharged at a pressure that is sufficient for use in the fuel cell stack. Water is injected into the compressor. Vaporizing is achieved using heat generated through compression. A compression pressure of the compressor is adjusted based on a quantity of the water to vaporize the water therein.
