Abstract
A power generating system which comprises a fuel cell and a rechargeable storage battery coupled together via a DC-DC converter. A reactant for the fuel cell is obtained by processing a suitable raw material. The processor is controlled on the basis of the current demanded by the external load and by the storage battery, and the fuel cell current drawn by the DC-DC converter is controlled on the basis of the amount of reactant available from the processor.
