The fuel processor system of the invention generates hydrogen from a hydrocarbon
compound or from mixtures of hydrocarbon compounds for generating electric energy
and heat by way of a combustion path, along which the generated hydrogen is passed
for combustion. Included in the combustion path is at least one fuel cell for generating
electric energy. The system further includes a first heat exchanger and a second
heat exchanger, which, on the one hand, are series included in the combustion path
downstream of the fuel cell. The first heat exchanger exchanges heat between the
combustion path and a first heating circuit which includes the fuel cell. The second
heat exchanger exchanges heat between the combustion path and a second heating
circuit which includes the fuel processor. The generated hydrogen undergoes combustion
where the fuel cell assists in generating electric energy and, optionally, the
fuel processor assists in generating heat.
