1,178,053. Fuel cells. ESSO RESEARCH & ENG. CO. 22 Sept., 1967 [29 Dec., 1966], No. 43279/67. Heading H1B. [Also in Divisions C1 and C7] Fuel cells are provided with an anodic oxidation catalyst comprising a transition or post transition metal mixed metal oxide tungsten bronze in which the atomic ratios of the components are represented by the formula T x WO y , wherein T is a transition, or posttransition metal as hereinbefore defined, x has a value greater than 0À2 and up to 1 when T is nickel, and from 0À2 to 1 when T is a metal other than Ni, and y is 2-4. Example 1 describes the use of an Ni mixed oxide tungsten bronze loaded with P.T.F.E. on to a Ta screen and used as an anode in a half cell employing 30 wt. per cent aqueous H 2 0 4 at 90‹ C. and N 2 , H 2 , CH 3 OH and H 2 C = CH 2 as fuel. |
