“…Airlines are dependent on the water quality the airports supply and do not have the ability to control water quality themselves. In some cases water quality provided by the airports is unsatisfactory and may be contaminated with bacteria, which can endanger passenger health [15].

Implementing a proton exchange membrane fuel cell (PEMFC) into an aircraft environment is a challenging task. In order for aircraft manufacturers and airlines to realize the ecological and economic benefits of this technology, it is necessary to make use of the multiple functions that a fuel cell system can provide. In addition to the main product of electrical energy, the fuel cell is capable of delivering further products, which are useful in an aircraft environment. The waste products -water vapor, heat and oxygen-depleted air (ODA) -at the cathode exhaust are valuable for use on board a commercial airplane. This paper describes the multifunctional approach, points out the advantages of the operation strategy as well as describes a prototype system for the multifunctional use of a PEM fuel cell on board a commercial airplane. The stable operation of the aforementioned system was successfully demonstrated in various tests. The emphasis of the work in question is on water and ODA generation/conditioning.

“…Currently the hydrogen storage method for fuel cell powered vehicles seems to be 70 MPa compressed hydrogen [9]. Whereas the liquid hydrogen storage has been discussed to be used in aviation systems [29,37], the solid hydrogen storage in metal hydrides has already been implemented in submarines powered by fuel cells [27,30]. Besides of their high volumetric hydrogen storage density, metal hydrides offer high heat storage capacities [5,40].…”

PEMFC for aeronautic applications: A review on the durability aspects

Proton exchange membrane fuel cells (PEMFC) not only offer more efficient electrical energy conversion, relative to on-ground/backup turbines but generate by-products useful in aircraft such as heat for ice prevention, deoxygenated air for fire retardation and drinkable water for use on-board. Consequently, several projects (e.g. DLR-H2 Antares and RAPID2000) have successfully tested PEMFC-powered auxiliary unit (APU) for manned/unmanned aircraft. Despite the progress from flying PEMFC-powered small aircraft with 20 kW power output as high as 1 000 m at 100 km/h to 33 kW at 2 558 m, 176 km/h [1-3], durability and reliability remain key challenges. This review reports on the inadequate understanding of behaviour of PEMFC under aeronautic conditions and the lack of predictive methods conducive for aircraft that provide real-time information on the State of Health of PEMFCs. Highlights: The main research findings are -To minimize performance loss due to high altitude and inclination by adjusting cathode stoichiometric ratio. -To improve quality of oxygen-depleted air by controlling operating temperature and stoichiometric ratio. -Need to devise real time prediction methods conducive for determining PEMFC SoH in aircraft.
