A method for generating energy in mobile applications, such as water vehicles, wherein hydrogen is produced by at least partially dehydrogenating a hydrogenated liquid organic hydrogen carrier (LOHC) in a chemical reactor, where electricity and water are generated in at least one fuel cell and heat for the chemical reactor is generated in a heating device from the produced hydrogen, and where the hydrogen produced by the chemical reactor is first conducted through the at least one fuel cell and then supplied to the heating device, such that the at least one fuel cell can therefore be operated under partial load and thus with better efficiency than if the hydrogen for the heating device is branched off before the fuel cell.

An electrochemical reactor designed to increase the efficiency of hydrogen production from faeces and urine (excrement) is disclosed. Said reactor comprises two half-cells separated in a selective manner, a membrane systems separating the half-cells (comprising a proton-exchange and an anion-exchange membranes) and a system of electrical bridges that allow two mutually perpendicular electrical fields to be formed, with the electrical field in the horizontal direction between the two half-cells being greater than the vertical electrical field generated within the anode. The half-cells have a configuration of two resistances in series, which allows the potential of each compartment to be controlled in an independent and complementary manner by adjusting the conductivity of the solutions in the half-cells. Said configuration allows the consumption of energy to form hydrogen to be significantly reduced in comparison with conventional electrolytic cells using water in an alkaline medium by combining the chemical processes of electrolysis (anode) and the law of chemical equilibrium (cathode).
