Abstract
The porous hydrogen gas diffusion electrodes employ skeletal nickel as catalyst. They show a potential of -800 mV vs Hg/HgO
at a c. d. of 30-35 mA. cm-2. In order to improve their performance platinum is incorporate&in the matrix in different quantities
ranging from 0.5 to 2.0 mg. cm-2. The electrochemical behaviour of these electrodes are compared with the method
of deposition of platinum. Current densities greater than 50 mA. cma were achieved and the optimum of platinum catalyst
is reported
