To develop the numerical simulation of PEM fuel cell, verification experiments and data acquisition of physical parameters were conducted by mechanical and electrochemical measurements. The mechanical measurement showed that the GDL deformation due to clamping by separator lands is important phenomenon to estimate an actual flow in the cell, and the unique deformation behavior of GDL with fabric construction was clarified. From the electrochemical measurement, the methods to acquire the parameters used in the simulation, proton conductivity σ_m, electrochemically active Pt area a, exchange current density i_o and cathode transfer coefficient α_c were established. Furthermore, the possibility to analyze flooding phenomenon by applying this electrochemical measurement was presented.
