Fuel cell system and appropriate operating method

摘要

The system has a reformer (3) for gaseous fuel production from oxidizer gas and fuel and comprising an oxidizer input (13), fuel input (12) and gaseous fuel output (17). A gaseous fuel line (18) connects the gaseous fuel output with an anode input (4) of a fuel cell (2). A fuel cell output gas line (31) is attached over an anode output gas line (29) to an anode output (5) and over a cathode output gas line (28) to a cathode output. A bypass line (44) is connected with the fuel cell output gas line and the gaseous fuel line. An independent claim is also included for a method for disconnecting a fuel cell system.
