Chromium-doped Raney nickel catalyst for hydrogen electrodes in alkaline fuel cells

Raney nickel is a relatively inexpensive and highly active non-noble metal catalyst for hydrogen electrodes in alkaline fuel cells. During the course of attempting to add various dopants to Raney alloys, the author has found that tenth percents of chromium markedly enhance the activity of Raney nickel. Hydrogen electrodes catalyzed with this new Raney nickel have been prepared, and their polarization characteristics have been measured. For comparison, the polarization data are shown with those for titanium-doped and nondoped Raney nickels which undergo the same electrode processing.
