Hydrogen fuel reforming in a fog cooled fuel cell power plant assembly.

摘要

The power section (2) of a phosphoric acid fuel cell power plant is cooled by injection of water droplets or fog (36) into the anode gas stream, wherein the water droplets are vaporized. The anode exhaust with the water vapor therein is then split with a portion (46) thereof being directed to the burner (23) in the catalytic reformer (22) to be consumed by the reformer burner. The remainder of the anode exhaust (44) is routed to the reformer inlet where it provides the water necessary for the reforming reaction. The fog is produced by condensation of water out of the exhaust (58) from a turbocompressor (12) which compresses the air supply (8) for the cathode side (4) of the power section.
