Abstract
Particularly in the case of a fuel cell, the waste gas contains, in essence, carbon dioxide and methanol. According to the invention, the carbon dioxide/methanol gas mixture is directed through a porous material and is scrubbed out in the counter-current flow using water. The device utilizes a gas scrubber to separate out the fuel.

- passing an off-gas primarily containing carbon dioxide and the fuel in a carbon dioxide/fuel mixture through a porous material;
- and
- pumping water in countercurrent to the off-gas, and substantially completely taking up the fuel from the carbon dioxide/fuel mixture.
