Abstract
A plurality of fuel-cell stacks operated in electrically parallel connection are individually controlled for amounts of reaction gases fed thereto corresponding to ratios of allotment of load thereto such that each of the stacks can maintain standard gas utilization factor. Among the fuel-cell stacks operated in parallel connection, those stacks which have particularly small ratios of allotment of load are controlled so that their gas utilization factors are changed to be decreased, thus controlling the amounts of the reaction gases to be increased.
