Electrochemical generator based on solid oxide fuel cell and hydrogen aluminum reactor for hydrogen production
https://doi.org/10.15518/isjaee.2023.04.103-112
Abstract
A cogeneration power plant based on a solid oxide fuel cell with an aluminum-hydrogen reactor in which hydrogen is obtained from aluminum and water in the presence of alkali is described. The efficiency of such a reactor is 43.7%. The fuel utilization rate at a power plant with an electric capacity of 10 kW is 42.3%. The electrical efficiency of the fuel cell is 77.2%, the proportion of hydrogen oxidized in the anode is 80.5%. The specific consumption of conventional fuel for the production of electric energy is 0.283 kg. t., and for the production of thermal energy 78.7 kg.t./ GJ.
Specific indicators are higher compared to similar indicators for cogeneration power plants running on hydrocarbon fuel, but less than in the Russian energy system – 0.33 kg cubic tons/ kWh.
