<p>A device for generating electric power by means of a fuel cell, comprising: a fuel supply connection (2) for supplying substantially gaseous fuel to the fuel cell (1); an air supply (3) connection for supplying to the fuel cell a gas which is at least partially formed by oxygen; an air discharge (4) connection for discharging from the fuel cell the part of the gas which is supplied via the air supply connection and not used in the fuel cell; and an outlet connection (5) for discharging from the fuel cell the reaction products of the fuel cell, wherein the device comprises: a separating device (9, 11) connected to the outlet connection of the fuel cell for separating the combustible gases from the gases supplied via the outlet connection; and a supply device for supplying to the fuel supply connection the combustible gases coming from the separating device. These measures have the result that particularly the combustible gases which are present in a low concentration at the end of the fuel cell are 'reprocessed' into gases with a higher concentration of such combustible gases, so that they can be fed back to the beginning of the fuel cell together with 'fresh' fuel.</p> |
