Abstract
A fuel cell system is provided with a fuel cell, a fuel gas supply line supplying fuel gas to the fuel cell, an oxidizing gas supply line supplying oxidizing gas to the fuel cell, a circulation line circulating fluid through at least one of the fuel cell, the fuel gas supply line and the oxidizing gas supply line, and a microorganism inhibiting unit located in the circulation line to execute sterilization so as to sterilize microorganisms present in the fluid. The microorganism inhibiting method is utilized in the fuel cell system of such a structure to sterilize the microorganisms present in the fluid in the midway of the circulation line.
Claims18
A fuel cell system comprising:
- a fuel cell;
- a fuel gas supply line supplying fuel gas to the fuel cell;
- an oxidizing gas supply line supplying oxidizing gas to the fuel cell;
- a circulation line circulating fluid through at least one of the fuel cell, the fuel gas supply line and the oxidizing gas supply line, the fluid being supplied into and discharged from the at least one of the fuel cell, the fuel gas supply and the oxidizing gas supply line as circulating liquid;
- and
- a microorganism inhibiting unit located in the circulation line to execute sterilization so as to sterilize microorganisms present in the circulating liquid discharged from the at least one of the fuel cell, the fuel gas supply line and the oxidizing gas supply line to be supplied into the at least one of the fuel cell, the fuel gas supply line and the oxidizing gas supply line through the circulation line.
A fuel cell system comprising:
- a fuel cell;
- fuel gas supply means for supplying fuel gas to the fuel cell;
- oxidizing gas supply means for supplying oxidizing gas to the fuel cell;
- circulation means for circulating fluid through at least one of the fuel cell, the fuel gas supply means and the oxidizing gas supply means, the fluid being supplied into and discharged from the at least one of the fuel cell, the fuel gas supply means and the oxidizing gas supply means as circulating liquid;
- and
- microorganism inhibiting means for executing sterilization so as to sterilize microorganisms present in the circulating liquid in a midway of the circulation means.
A method of inhibiting microorganisms in a fuel cell system, the method comprising:
- preparing a fuel cell;
- preparing a gas supply line supplying fuel gas and oxidizing gas to the fuel cell;
- circulating fluid through at least one of the fuel cell and the gas supply line, the fluid being supplied into and discharged from the at least one of the fuel cell and the gas supply line as circulating liquid;
- and
- sterilizing the microorganisms present in the circulating liquid in a midway through which the circulating liquid is circulated.
