Abstract
A method and apparatus is disclosed for operating a fuel cell 14 which produces electrical energy in combination with an electrochemical cell 12 which uses electrical energy to produce a chemical product. A direct current converter 16 intermittently passes electrical power from the fuel cell to the electrochemical cell to enable the fuel cell to operate at a desired voltage which is independent of the voltage for the electrochemical cell. This permits the fuel cell to operate within a schedule of desired operating voltages.
