A process to desulphurize a fuel gas, such as natural gas, for use as a feed fuel for a fuel cell. A feed stream (10) of sulphur-containing gas, is partially passed (12) to a compressor (14), then to a sulphur selective membrane (16) to provide a sulphur rich stream (18) which is returned to the feed stream (10), and a sulphur lean stream (20) which can be passed to an optional gas meter (26) and then to a sulphur-sorbent medium (28) before reforming the essentially sulphur-free stream (34) in the reformer (40) of a fuel cell unit (36) also containing a fuel cell (38). <IMAGE> |
