Abstract:
1. A method of shutting down a hydrogen generator, the hydrogen generator including a reformer having a reforming catalyst body configured to generate a hydrogen-rich gas from a combustible feed gas and water, and a burner configured to heat said reforming catalyst body heat-exchangeably, the method comprising the steps of: purging an interior of said reformer by supplying the combustible feed gas to an interior of said reformer; and diluting the concentration of a combustible gas in a mixed gas containing the feed gas sent out from said reformer and air inside said burner to be less than the combustible concentration by increasing an amount of air supplied to an interior of said burner when purging the interior of said reformer.
