Abstract
In the present study, using a variation of rib height, the transient response and the performance are investigated. The cell voltage is acquired according to the current density change(0.8A/cm2 to 1.0A/cm 2) under same stoichiometry and relative humidity. The different level of undershoots appeared at the different clamping pressure(1.5MPa and 2.0MPa) and different rib height. At 1.5MPa clamping pressure, rib manufactured cut at 100μm height goes to steady state faster than reference plate and has lower maximum undershoot voltage. But performance is lower than reference plate due to increasing contact resistance.
