ABSTRACT:
An energy conversion system comprising ammonia for fueling an SOFC stack to generate electricity and a hydrogen-rich tailgas. In the SOFC stack, ammonia is cracked to hydrogen and nitrogen. Ammonia is stored in a metal halide complex and is released therefrom as gaseous ammonia by waste heat from the SOFC. A heat exchanger is positioned across the SOFC cathode such that incoming air is tempered by the cathode exhaust air. In a two-stage energy conversion system, the hydrogen-rich tailgas from the SOFC is supplied as fuel to a secondary energy conversion device which may be, for example, an internal combustion engine or a gas turbine engine which may operate, for example, either a generator for generating additional electricity or a vehicle for motive power, or a second fuel cell stack.
