Alfa Chemistry Materials Launches Fuel Cell Catalysts for Renewable Energy Industry
By: Alfa Chemistry
Fuel cell directly converts the chemical energy of fuel into electrical energy, and it is viewed as inherently safe power generator device for energy that is cost-saving and ecological environment protective.
"In order to improve fuel cell performance, catalysts are introduced. At present, platinum and its alloys are the most commonly used catalysts for different types of fuel cells at both the anode and the cathode," says one of the senior scientists from Alfa Chemistry Materials. "To select the most appropriate catalyst, a number of criteria should be taken into consideration, such as electrical conductivity and surface characteristics. Platinum becomes the first choice in mind because it conducts electricity, catalyzes reactions with aplomb, and is hard enough to survive the harsh and acidic environment of a fuel cell."
However, since platinum catalysts are prohibitively expensive, researchers resort to other catalyst replacements that can catalyze fuel cell reactions at a lower cost but without compromise in efficiency.
Based on the existing research, fuel cell catalysts can be divided into the following types:
Transition metal chalcogenide compounds
Although studies have shown that Mo4Ru2Se8 possess cathodic catalytic activity under acidic conditions, these metal chalcogenide compounds are easily oxidized, which hampers the likelihood of replacing Pt-based catalysts with them.
At Alfa Chemistry, varieties of fuel cell catalysts are now readily available. To name just a few here: platinum single crystal disc, 10 mm (0.39 in) in diameter, 1-2 mm (0.04-0.08 in) in thickness, (110) orientation, nominal (CAS 7440-06-4), nickel on silica/alumina, ruthenium on carbon, ruthenium on alumina, rhodium on carbon, rhodium on alumina, platinum-ruthenium alloy on graphitized carbon, platinum on graphitized carbon, platinum, sulfided, on carbon, platinum cobalt on carbon, platinum on carbon (https://materials.alfachemic.com/
