First claim
Opening claim text (preview).
1 - 8 (canceled) 9 . A catalyst system comprising: a carbon-based support material; and a polyaniline-metal catalyst bound to the support material, the polyaniline-metal catalyst including iron (Fe) and manganese (Mn). 10 . The catalyst system as recited in claim 9 wherein the polyaniline-metal catalyst is a polyaniline-Mn/Fe catalyst. 11 . The catalyst system as recited in claim 9 wherein a molar ratio of Mn to Fe is in the range from 1:100 to 100:1. 12 . The catalyst system as recited in claim 11 wherein the molar ratio of Mn to Fe is in the range from 1:5 to 5:1. 13 . The catalyst system as recited in claim 12 wherein the molar ratio of Mn to Fe is in the range from 1:1.5 to 1.5:1. 14 . The catalyst system as recited in claim 13 wherein molar ratio of Mn to Fe is 1:1. 15 . The catalyst system as recited in claim 9 wherein metal amounts to a fraction of 10% to 40% by weight of the total weight of the catalyst system. 16 . A fuel cell comprising the catalyst system as recited in claim 9 .
