ELECTROCATALYST SUPPORTS FOR FUEL CELLS |
摘要 |
Titanium oxide (usually titanium dioxide) catalyst support particles are doped for electronic conductivity and formed with surface area-enhancing pores for use, for example, in electro-catalyzed electrodes on proton exchange membrane electrodes in hydrogen/oxygen fuel cells. Suitable compounds of titanium and a dopant are dispersed with pore-forming particles in a liquid medium. The compounds are deposited as a precipitate or sol on the pore- forming particles and heated to transform the deposit into crystals of dopant- containing titanium dioxide. If the heating has not decomposed the pore- forming particles, they are chemically removed from the, now pore-enhanced, the titanium dioxide particles. |
