Figure 6

Electrochemical measurements of the MEAs: (a,b) Polarization curves of a conventional MEA and the MEAs with cracks generated using a 20 μm prism pattern (a) and a 50 μm prism pattern (b) with various strains (~0.5 and ~1.0) under H2/air. (c) Oxygen gains obtained under ambient pressure. (d) Cyclic voltammetry (CV) measurements of the prism-patterned MEAs with the same strain (~0.5) and a conventional MEA at the cathode catalyst layers (NHE = normal hydrogen electrode).
