Supply system for fuel cells of the S.P.E. (solid polymer electrolyte) type for hybrid vehicles

摘要

A supply system for fuel cells of the solid polymer electrolyte type for vehicles, including a primary cooling and humidifying circuit with demineralised, pressurised water with a small volumetric capacity and a secondary liquid cooling circuit with plate exchangers for cooling the demineralised water of the primary circuit and air/liquid exchangers for cooling compressed air for supply to the cells, the system further including an electric heater for heating the liquid in the secondary circuit so that the cells can be put into service quickly and means for recycling hydrogen leaving the cells to make the optimum use of the fuel.
