Clamping mechanism is one of the most important parts of the Polymer electrolyte membrane (PEM) fuel cells. Importance of clamping mechanism is because of the contact pressure distribution over the gas diffusion layers (GDLs). The aim of this paper is to study the contact pressure distribution over the active area of PEM fuel cell using FUJIFILM pressure distribution mapping system. The experimental setup is proposed to investigate the contact pressure distribution of membrane electrode assembly (MEA). The contact pressure distribution over the active area of the PEM fuel cell is obtained using super low pressure (LLW) measurement films. There is a relationship between the color density of the pressure measurement films and the pressure level. Pressure distribution mapping system scans the pressure measurement film and converts this into pressure values.
