Abstract
Catalytic layers for fuel cells are formed by co-depositing platinum or gold from a combustion chemical vapor deposition flame and carbon particles and ionomer from a non-flame, co-deposition flame. A layer having high platinum or gold loading with high particulate size is deposited. Such layers have high efficiency, whereby the total amount of platinum or gold used in a fuel cell may be reduced.
