Abstract

The electrochemical properties for Ni Raney alloy were investigated related as potential applications in the fuel cells for low operating temperature conditions. The study compares two types of Ni-Raney where nickel powder as raw materials is in micron size, respective synthesized in microwave reactor. Nano-sized Ni Raney showed an increased catalytic activity when its grain size is below 150 nm. Cyclic voltammetry evaluated the electrochemical activity of the of both Ni-Raney structures showing an oxidation potential decreased from 703 mV to 203 mV.
