Fuel cell auxiliary power unit
A fuel cell auxiliary power unit (FC-APU) is a fuel cell based auxiliary power unit on a vehicle that provides energy for functions other than propulsion. They are mainly used in trucking, aviation, marine and recreational vehicles.<ref>fuel cells for auxiliary power unit applications Archived 2013-12-03 at the Wayback Machine</ref>
