MAINS-INDEPENDENT PORTABLE POWER GENERATION SYSTEM WITHOUT POLLUTANT EMISSION, AND METHOD FOR PRODUCING ELECTRIC CURRENT USING SAME

摘要

The invention relates to a mains-independent portable power generation system without pollutant emission, which comprises: a (PEM) fuel cell unit (1); a hydrogen storage facility (19); a line (22) for supplying hydrogen from the storage facility (19) to the anode chamber (2); a line (5) and a pump (9) for recirculating unreacted hydrogen from the anode chamber outlet to the anode chamber input; a line (25) and a pump (11) for supplying air to the cathode chamber (4); a line (6) for discharging cathode gas containing water vapour; a heat exchanger (20) which encloses the storage facility (19); a coolant circuit (18) with a pump (21) between the heat exchanger (20) and fuel cell unit (1); a device (16) for withdrawing current being generated; and a control/regulating unit (14) for controlling/regulating the hydrogen recirculation, air supply and coolant circuit in accordance with the setpoint cell voltage and setpoint cell temperature. The invention also relates to a method of producing electric current using the above power generation system.
