Abstract

In a method of producing porous sintered electrodes for fuel cells using Ni as a frame metal, up to 20 atom % of Ti, V, Cr, Co, Mo, Ru, or Ta is added to a procatalyst of a Pt group metal + Al or Pt group metal Ni + Al and the Al is etched away to leave a porous skeleton catalyst. 2-10 atom % of Ag may also be added to a Pd-Al alloy. The procatalysts are formed by melting a compact of the powdered elements in hydrogen. The following procatalyst compositions are given:- .Pd0.6.Co0.4.Al2.5. .Pd0.6.Ru0.4.Al2.5. .Pd0.7.Mo0.3.Al2. .Pd0.4.Ni0.4.V0.2.Al2.4 .Pd0.2.Ni0.6.Ti0.2.Al2.2\t .Pd0.2.Ni0.6.Ta0.2.Al2.2\t .Pd0.5.Co0.4.Ag0.1.Al2.5\t After cooling the procatalyst is crushed to particles of 20-40 microns and mixed with Ni and NaCl of 60-90 microns. A layer of Ni + NaCl powder is place over a layer of the mixture and the layers are compacted and sintered between perforated steel plates at 600 DEG C. in H2. The Al and NaCl are dissolved out in a solution of caustic soda and the catalyst is then provided with a frame and an output terminal and may be used as an anode for the electrochemical combustion of methanol. Further examples of the preparation of electrodes are given and in one three different powder layers are used.
