Abstract
A fuel cell system (1) with a fuel cell unit (2) including at least one fuel cell (3), as well as an anode gas feed (11) including a reformer (12). A reduced deposit of hydrocarbons on an anode (5) of the fuel cell (3), especially in case of a cold start of the fuel cell system (1), is achieved when the anode gas feed (11) has a reduction device (14), which is arranged between the reformer (12) and the anode (5).
Claims20
A fuel cell system comprising:
- a fuel cell unit comprising at least one fuel cell with a cathode, with an anode, and with at least two electric terminals for feeding an electric user;
- an anode gas feed means for feeding a reformate gas to the anode, the anode gas feed means comprising a reformer for producing the reformate gas and a reduction means for reducing the concentration of higher hydrocarbons in the reformate gas, the reduction means being arranged between the reformer and the anode.
A fuel cell system comprising:
- a fuel cell unit comprising at least one fuel cell with a cathode, with an anode, and with at least two electric terminals for feeding an electric user;
- an anode gas feed connected to the anode and feeding a reformate gas to the anode, the anode gas feed comprising a reformer producing the reformate gas and a reduction device receiving the reformate gas and reducing the concentration of higher hydrocarbons in the reformate gas to produce a reduced higher hydrocarbon reformate gas, the reduction device being arranged between the reformer and the anode and supplying reduced higher hydrocarbon reformate gas to the anode.
