A fuel cell, electrolyser or battery comprises a liquid electrolyte 202, a cathode and an anode. The cathode comprises a plurality of pipes 206a arranged, in use, to extend at least partially into the electrolyte, each pipe being arranged to allow oxygen to flow therethrough and having a permeable section, the permeable section being arranged, in use, to allow the oxygen to come into contact with the liquid electrolyte. The anode 204 comprises a plurality of elongate projections arranged, in use, also to extend at least partially into the electrolyte. These elongate projections may also comprise pipes, possibly with permeable sections in contact with the liquid electrolyte if desired. The fuel cell, electrolyser or battery may comprise a plurality of anodes 204 and cathodes 206a, arranged in the form of interleaving rows. The electrolyte 202 may be a molten carbonate or other molten salt, an ionic liquid and/or a salt solution. |
