In this research, a novel way to examine the elastic strain effect on a platinum catalysis surface during oxygen reduction reaction (ORR) has been developed. A NiTi shape memory alloy was selected as substrate to provide both tensile and compressivestrain by using the nature of two-way shape memory effect for the first time. The experimental results clearly show that the compressive strain can enhance the ORR activity, while the tensile strain has the opposite effect during ORR.
