“…The effects of the component thickness, elastic modulus and density on vibration modes were discussed. Deshpande et al [16] analyzed the modes of a PEMFC stack, and found that the hydrogen leakage rate increases linearly with vibration acceleration. Hong et al [17] found that even though a small change in the stack structure can result in a significant variation in local vibration modes.…”

“…In addition to these experimental studies, a few researchers have carried out simulations on PEMFCs under vibrations to predict their performance. In 2014, Deshpande et al 11 used the finite element method to analyze PEMFC stacks under vibration and observed that the hydrogen leakage rate increased linearly with vibration acceleration. In 2016, Liu et al 12 analyzed the response stress of the stacks under random vibrations by the finite element method (FEM) and assessed the fatigue lives of fuel cell components based on the Miner fatigue damage theory.…”

The effects of ship vibrations on the mass transfer and performance of proton exchange membrane fuel cells (PEMFCs) have many vague aspects. Hence, the method of loading ship vibrations with the sliding mesh is first proposed in this paper. Furthermore, this method is adopted to form the solution of the simulation study of PEMFC performance under ship vibrations. In the framework of computational fluid dynamics, the ship vibration is loaded into the three-dimensional PEMFC model and successfully solved. Then, a series of special cases are performed to explore the gas distribution and output features of PEMFCs in ship environments with different vibrations. Finally, the results show that the ship vibrations have vectorial effects on the gas transfer in the PEMFC. Additionally, vibrations perpendicular to the channel evidently affect the gas transfer. Moreover, while the vibrations are parallel to the channel, they remain nearly normal. Relatively, a more significant influence on the output voltage of the PEMFC will occur under smaller frequencies and/or greater amplitudes of ship vibrations.

“…Rajalakshmi et al [6] researched on the influence of the amplitude and frequency of mechanical vibration on the crack propagation rate based on a MEA numerical model. A single cell model is established for simulating by Deshpande et al [7], the results show that, after one hour vibration of 10 g, a slight movement of the seal causes the deterioration of airtightness and the displacement is considered to be linearly related to the acceleration amplitude; meanwhile the bolt torque is reduced by 20-25%. Jiang [8] established a three-dimensional finite element model containing 100 single cells; it was found that the mechanical impact resulted in interlayer slippage and global deformation of FCS.…”

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.
