Waste Heat Revalorization with Electric Generation Based on Fuel Cell

In the following article the joining of a system of electric generation is described with a thermal transformer by absorption (AHT). The electric system is formed by to cell of combustible type PEM in which is entered hydrogen and oxygen to pressures of the same order of magnitude. The heat that is necessary to release of the cell of fuel is given an AHT using the mixture aqueous lithium bromide. The mixture H2O/ LiBr has been selected by its smaller operation generation temperatures to 373 K. The results show the operation coefficient and the cogeneration coefficient in function of the temperature of operation of the cell of fuel (TFC) and the temperature of the surroundings (Tamb). The results show the obtaining of revalorized useful heat and electric power.
