Fuel cell system and method of operation

摘要

The method involves generating an electrical current by a fuel cell (2) from an anode gas containing hydrogen gas and a cathode gas containing an oxygen gas. The anode gas is generated from a fuel containing hydrogen and from an oxidator containing oxygen by a reformer (3). The hydrogen gas that contains anode exhaust gas of the fuel is burnt with the oxygen gas that contains cathode exhaust gas of the fuel using a residual gas burner (4), so that water is removed from burner exhaust gas of the residual gas burner, and is conducted to the fuel cell and/or the reformer. An independent claim is also included for a fuel cell system in a motor vehicle.
