“…Feasibility studies of MFC focus on produced water, heat and cathode exhaust gas management. For instance, tests carried out by [17] to study mechanical behaviour of fuel cell on a vibrating platform simulating aircraft conditions showed no significant damage on the fuel cell. The damage was estimated based on leak tests which showed no notable pressure changes [17].…”

“…The "elastic" stack resembles non-linear multibody behaviour that could decrease with increase in size of the stack [18]. Therefore rigidity and balance-of-plant fittings could become an issue for larger stack [17]. On the other hand, orientation and inclination tests showed voltage decrease at an angle of 30 ∘ when operated at a low air stoichiometry of 1.6 [7].…”

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.

“…A large number of literatures have shown that mechanical impact has an effect on the performance of fuel cell stack, but the internal structural distortion of FCS has not been analyzed in depth. Rouss et al [3,4] established a multiinput and multi-output fuel cell stack neural network model.…”

A simplified finite element model for large polymer electrolyte membrane fuel cell (PEMFC) stack consisting of ten cells is established in order to investigate the internal structure deformation. It is found that the interface slippage occurs when the bipolar plate (BP) and membrane electrode assembly (MEA) are subjected to vertical impact acceleration. Based on this three-dimensional model, the influence of the friction coefficient between BP and MEA on the relative slippage can be analyzed efficiently. The division layer of relative slippage is found and its vibration rule is discussed. It is observed that increasing the magnitude of impact vibration has most significant effect on the movement of the division layer, and the two variables are linearly related when impact acceleration is greater than 5 g. This work provides important insight into the choice of the friction coefficient.

“…Thus, the characterisation methods developed are essentially for static stress conditions. Furthermore, in transportation, fuel cell systems are also excited by vibrations and consequently the different components also endure these vibrations [25,26]. These vibrations have a significant influence on the overall PEMFC performances [27].…”
