METHOD OF CARBON-BEARING FUEL USAGE TO INCREASE THE EFFICIENCY IN TANDEM DIVERSE TEMPERATURE OXIDATION SYSTEM
This paper presents the results of estimation energy efficiency, the adjusted data of thermodynamic calculations and data on material and energy balances for an assessment of electric and thermal components in considered method of fuel usage, performance enhancement in the tandem system containing the high-temperature fuel cell and the low-temperature fuel cell with full heat regeneration for carbon-bearing fuel (methane (CH4)). The overall effective efficiency (ηΣef., making full usage of the recovered heat) of the considered tandem system depends on the efficiency of its constituent fuel cells. The overall effective efficiency of the tandem installation including the fuel converter, separating system, high-temperature oxidation system, and hydrogen disposal system – in case of fuel use in the low-temperature fuel cell – is higher than for each of the fuel cell elements separately.
