Abstract:The safety issues for use of a proton exchange membrane fuel cell (PEMFC) system providing onboard electrical power for a commercial aircraft has been evaluated. Teledyne Energy Systems, Inc. performed a failure mode and effects analysis on each of two potential applications. One PEMFC system was designated and designed for an application inside the aircraft cabin area and the other outside the aircraft cabin. These applications represent systems that require different levels of integration into the aircraft structure and represent electrical power requirements that are either critical or nonessential to safe aircraft operation. The operational risks identified for each application are similar, but the overall safety consequences are significantly different.
