This technology is related to the development of a highly innovative, energy efficient and environmentally friendly power production unit for decentralized (on or off grid) power generation. The unit has the capability for combined heat and power (CHP) production, as needed. The device is able to convert the fuel (LPG/NG/Biogas) into electrical and thermal power by means of a PEM fuel cell, with intermediate production of hydrogen. The nominal capacity of the power system is 5 kW, while, in the ...
