Abstract
High temperature reducing gas is supplied to a reforming catalyst (51) of a reformer (13) and a CO removal catalyst (52) of a CO removal device (15) from a start-up combustor (11). By supplying the high temperature reducing gas from the start-up combustor (11), there is no need to provide an additional device for supplying reducing gas, and the heat required for the reaction may be supplied simultaneously.
Claims12
A drive system for a fuel cell, comprising:
- a catalyst reaction part which has a catalyst and generates gas supplied to the fuel cell by a catalytic reaction in the catalyst;
- a start-up combustor which is provided upstream of the catalyst reaction part and receives a supply of fuel and air to perform combustion;
- and
- a controller functioning to:
- generate high temperature reducing gas in the start-up combustor by burning the supplied fuel and air, and
- supply the high temperature reducing gas to the catalyst reaction part, and reduce the catalyst in the catalyst reaction part.
