High temperature fuel cell e.g. solid oxide fuel cell, operating method for internal combustion engine, involves cooling mixture from exhaust gas and fuel using amount of air in exchanger, before entering mixture into compressor

摘要

The method involves recycling a part of a hot anode exhaust gas into an anode circuit (A). A liquid fuel upstream of a compressor (4) is injected into the hot anode exhaust gas, so that a liquid fuel (B) i.e. diesel, is completely evaporated. Mixture from the anode exhaust gas and fuel is cooled using an amount of air in a heat exchanger, before entering the mixture into the compressor that is connected upstream of a reformer (2). An amount of air needed for a reformation of the liquid fuel is added to the mixture from anode exhaust gas and fuel before compression.
