<P>PROBLEM TO BE SOLVED: To provide a hydrogen supply system capable of keeping constant odorant concentration in hydrogen circulating in a PEFC, and also, without exhausting the odorant out of the system. <P>SOLUTION: The hydrogen supply system is equipped with a circulating path 2 circulating hydrogen in a PEFC1, a supply path 3 supplying the stored hydrogen in a tank 6 to the circulating path 2 and a purge path 4 exhausting the hydrogen released from the PEFC1 out of the system. An odorant concentration control means 5 provided at the supply path 3 controls the odorant concentration of the hydrogen at the downstream of the odorant concentration control means 5 within a given range, and a first deodorizing means 8 provided at the purge path 4 eliminates the odorant from the hydrogen released out of the system. <P>COPYRIGHT: (C)2004,JPO |
