The sizes of the channel were calculated from the straight
sections of the 25 cm2 unit cell channel. The width of the
cathode was 1 mm and its length was 1 mm. The width of
anode was 1 mm and its length was 0.6 mm. The ribs were
structured every 0.5 mm on both sides of the channels. The
thickness of the gas diffusion layers was 0.3 mm, that of the
catalyst layers was 0.01 mm and that of the membranes was
0.05 mm.
