The cell stack is also responsible for a reasonable portion of the unit cost of VRFBs and comprises several key components. This includes the membrane, bipolar plates, electrodes, gaskets, and sealants.
End plate is one of the main components of the proton exchange membrane (PEM) fuel cells. The major role of the end plate is providing uniform pressure distribution between various components of the fuel cell (bipolar plates, etc.) and consequently reducing contact resistance between them.
A fuel cell stack is configured to power any load ranging from watts to megawatt by varying cells connected in series.
End plate is one of the main fuel cell components which has some important roles in a PEMFC stack such as unitizing various components (membrane-electrode assembly (MEA), gas diffusion layer (GDL), bipolar plate, etc.) to be a stack, providing passages for reactant gases and coolant fluid and ensuring good sealing at various interfaces ( Fig. 1 a).
Asghari et al. use the finite element method to analyze the influence of the thickness of the endplate on the deformation of the bipolar plates of the fuel cell stack. In this model, the optimal thickness is 35 mm, and the internal resistance of a fuel cell stack with 5 kW is tested under different clamping torques.
Experimental validation has been carried out using a fuel cell with SS-316 end plates and bipolar plates made of graphite. The carbon paper based MEA is sandwiched between the two bipolar plates, with a pressure sensitive film inserted between them. The pressure sensitive film used is Fuji Film PRESCALE, Japan (LW and LLW).
The results showed that pressure plate tightening is better in improving the power of the fuel cell stack, and the uniform distributed pressure is beneficial to avoid excessive deformation of the MEAs, thereby ensuring the porosity of the GDLs.
