Simulation and experimental analysis of the clamping pressure distribution in a PEM fuel cell stack

Model-supported characterization of a PEM water electrolysis cell for the effect of compression

“…Additionally, the pressure distribution is generally a topic of interest which is investigated and opti- [23,24]. Different approaches in fuel cell research can be found in the literature, which can be transferred to electrolysis research.…”

Experimental determination of optimal clamping torque for AB-PEM Fuel cell

“…They performed experimental testing of clamping pressure effects on a 16-cell stack by placing a thin pressure-sensitive film between GDL and bipolar plate. They applied clamping pressure using various loads, durations, and two types of GDL resulting in detailed 3D plots of stress and deformation [2]. Chang et al [3] measured the electro-physical properties of the gas diffusion layer (GDL) such as porosity, gas permeability, electrical resistance and thickness using a special designed test rig under various clamping pressure levels.…”

Autocorrelation standard deviation and root mean square frequency analysis of polymer electrolyte membrane fuel cell to monitor for hydrogen and air undersupply

“…Work along similar lines was done by Bates et al who studied both analytically as well as experimentally the effect of clamping pressure and contact resistance on PEMFC performance [47]. Results indicate that there is a greater load distribution and hence stress concentration at the center of fuel cell stack than at the ends for both simulation and experiment [47]. The catalyst is an important part of the PEMFC and its degradation was studied in detail by Lee et al [48].…”

“…They developed a novel ex-situ flow mapping technique for this purpose [46]. Work along similar lines was done by Bates et al who studied both analytically as well as experimentally the effect of clamping pressure and contact resistance on PEMFC performance [47]. Results indicate that there is a greater load distribution and hence stress concentration at the center of fuel cell stack than at the ends for both simulation and experiment [47].…”
