| 摘要 |
The invention relates to a fuel cell system (1), which is suitable for operating by meas of a cathode operating gas containing oxygen and inert gas and by means of an anode operating gas containing hydrogen and inert gas. The invention further relates to a load system, which is operated by means of the fuel cell system (1), and to a method for operating the fuel cell system (1). In the method according to the invention, the individual components of the operating gases are stored separately and are mixed in the necessary amount fractions during the operation of the fuel cell system, wherein the inert gas fraction of the operating gases is continuously recirculated. During the operation of the fuel cell system, gases are neither taken in from the environment nor discharged to the environment, and fuel cell exhaust gases are not stored in the fuel cell system or the load system. In an alternative variant, only the anode operating gas is mixed and recirculated, while the cathode operating gas is drawn from the environment and the cathode exhaust gas is discharged to the environment. |
