Abstract

A fuel cell system has a single-stage or multistage gas generation unit for producing a hydrogen-rich gas from an untreated fuel, a single-stage or multistage gas cleaning unit, at least one fuel cell and a single-stage or multistage exhaust-gas treatment unit for converting the fuel cell exhaust gases as completely as possible. At least two sub-units of the fuel cell system are connected to one another mechanically and in terms of flow by means of a connecting plate.
