This document defines the technical guidelines for the safe integration of Proton Exchange Membrane (PEM) Fuel Cell Systems (FCS), fuel (considered to be liquid and compressed hydrogen storage types only), fuel storage, fuel distribution and appropriate electrical systems into the aircraft.
Editorial Note: Today PEM systems and fuel storage represent the most mature FCS technology and currently forms the basis for this standard. Other types of fuel cell systems and fuels (including reforming technologies and electrolyzers), may be covered by a further update to this document.
Rationale:
This SAE Aerospace Information Report (AIR) is intended to provide comprehensive reference and background information pertaining to the installation of fuel cells on-board aircraft for the purposes of supplying auxiliary power rather than using separate ground power systems.
