Fuel cell exploits carbon fibre molecular sieve

摘要

A UK-based manufacturer of fuel cells, ZeTek Power; is using carbon fibre composites developed by Oak Ridge National Laboratory (ORNL) in its alkaline fuel cell.At the heart of ZeTek's alkaline fuel cell system are two related technologies developed by ONRL:· electrical swing adsorption--this removes carbon dioxide from the fuel (hydrogen from natural gas, propane and other readily available gases) and from air by passing an electric current through a molecular sieve made using a composite based on carbon fibre. In turn, this avoids the release of carbon dioxide into the environment.· a method for manufacturing the carbon fibre elements through a slurry moulding process.
