HYDROGEN PRODUCTION METHOD, ENERGY PRODUCTION METHOD IN A HYBRID VEHICLE, ENERGY PRODUCTION SYSTEM IN A HYBRID VEHICLE, AND HYBRID VEHICLE

The present invention pertains to the electric energy industry, more specifically to an ethanol dehydrogenation system which converts ethanol into a more energy-rich fuel for use in combustion engines, at the same time as producing hydrogen without carbon monoxide, which is led to a fuel cell for producing electric energy for the subsequent electric and/or hybrid propulsion of motor vehicles. The present invention preferably relates to a method for producing energy in a hybrid vehicle, comprising the following steps: (a) providing a catalytic reactor (5); (b) feeding the catalytic reactor (5) with a stream of evaporated fuel; (c) leading the evaporated reagents to the catalytic reactor (5); (d) performing liquid fuel dehydrogenation reactions in the catalytic reactor (5); (e) cooling the output stream so as to separate the gaseous stream (9) from the liquid fuel stream; (f) supplying the liquid stream to an internal combustion engine (8) to generate energy, or returning the liquid stream to the catalytic reactor (5); (g) capturing an air stream (11); and (h) leading the gaseous stream (9) to the anode of the fuel cell (10) and the air stream (11) to the cathode of the fuel cell (10) to generate electric energy. In addition, the present invention describes a system for producing energy in a hybrid vehicle and a hybrid vehicle which use this method.
