Abstract
A fuel cell system includes a reformer, a fuel cell, a desulfurizer, a recirculation passage through which the reformer communicates with the desulfurizer such that a part of the anode gas generated in the reformer flows into the desulfurizer, and an orifice member provided on the recirculation passage. The orifice member or at least a part of an inner wall of a portion that constitutes an upstream side from the orifice member in the recirculation passage is made of a material containing a material having an antifungal action.
Claims4
A fuel cell system comprising:
- a reformer configured to generate an anode gas containing hydrogen by reacting fuel gas with water vapor;
- a fuel gas passage for supply of the fuel gas to the reformer;
- a fuel cell configured to generate electricity by electrochemically reacting oxygen with the anode gas generated by the reformer;
- a desulfurizer provided on the fuel gas passage and configured to desulfurize the fuel gas flowing through the fuel gas passage using hydrogen;
- a recirculation passage through which the reformer communicates with the desulfurizer such that a part of the anode gas generated in the reformer flows into the desulfurizer;
- and
- an orifice member provided on the recirculation passage, wherein the orifice member or at least a part of an inner wall of a portion that constitutes an upstream side from the orifice member in the recirculation passage is made of a material containing a material having an antifungal action.
