ABSTRACT:
A method and apparatus is disclosed for operating a fuel cell 14 producing electrical energy in combination with an electrochemical cell 12 using electrical energy to produce a chemical product. The electrolysis cell produces hydrogen for use as a fuel in the fuel cell and is linked with the fuel cell by a direct current converter 16 which allows the fuel cell to operate between an upper voltage limit and a lower voltage limit. The direct current converter 16 employs a gated switch means, such as a thyristor 98, to intermittently pass electrical power from the fuel cell to the electrochemical cell such that the voltage drop across the direct current converter is equal to the difference in voltage between the fuel cell and the electrochemical electrolysis cell.
