Abstract
The invention relates to a fuel cell system () suitable for operation with a cathode operating gas containing oxygen and inert gas and an anode operating gas containing hydrogen and inert gas; an appliance system operated by means of the fuel cell system (); and a method for operating the fuel cell system (). In the method according to the invention, the single components of the operating gases are stored separately, and mixed to the required portions during operation of the fuel cell system, thereby constantly recirculating the inert portion of the operating gases. During operation of the fuel cell system, gases are neither taken in from the environment nor released into the environment nor are fuel cell exhaust gases stored in the fuel cell system or the appliance system. In an alternative variation, only the anode operating gas is mixed and recirculated, while the cathode operating gas and the cathode exhaust gas are taken from the environment and released into the environment, respectively.
