Device for operating fuel cell in a heating system, comprises combustion device for heating up a heating substance and steam reformer fed with steam and fuel to deliver hydrogenous reformat to fuel cell.

摘要

A vaporizer (3) heated up by a combustion device (1) feeds steam to a steam reformer (4). Waste gas from the anode (14.1) of a fuel cell (14) is fed to a burner (1.1) for the combustion device for post-combustion. The vaporizer lies in a direction of flow of a combustion gas (d) in front of heat exchanger surfaces (1.6) heating a heating substance (c) and has a hot-water chamber and coiled tubing in the combustion gas. A condensate (l) fed to the vaporizer originates from the waste gas (k) from a cathode (14.3) in the fuel cell.
