| چکیده مقاله |
| One of the parameters that play an important role in the efficiency of fuel cells is the contact resistance between the fuel cell plates, which causes ohmic losses in the fuel cells. The ohmic resistance decreases with increasing compressive stress between the two plates and make full contact between them. On the other hand, with increasing pressure, the amount of porosity in the gas diffusion layer is reduced and the active area is reduced, thus reducing the efficiency of the fuel cell. In this research, contact pressure distribution on the Membrane Electrode Assembly in a three-cell fuel cell stack with metallic bipolar plates with an active area of 100 cm^2 has been studied experimentally. To experimentally investigate the distribution of contact pressure on the Membrane Electrode Assembly, a pressure sensitive film of Fujifilm Company has been used. Due to the fact that the stack consists of three cells, Pressure film is used in the middle cell. |
