PolyFuel Launches “Drop-In” Hydrocarbon Membrane to Substitute for Fluorocarbons MOUNTAIN VIEW, CA - Membrane developer PolyFuel Inc. here has developed a new variant of its hydrocarbon membrane engineered for portable applications that it says makes it possible to substitute them directly for traditional fluorocarbon membranes in manufacturing membrane electrode assemblies (MEAs).
Laminar-Flow Micro Fuel Cell Eliminates Membrane, Can Use Alkaline Chemistry CHAMPAIGN, IL/CARY, NC - A team of scientists at the University of Illinois at Urbana-Champaign (UIUC) has come up with a novel micro fuel cell design that not only does away with the conventional membrane - and problems such as methanol crossover - but that can also function either as an alkaline or acidic system.
Aging PEM Catalysts, Solar Electricity Prospects Described in MIT Publication CAMBRIDGE, MA - Platinum catalyst particles change size and location over time in a PEM fuel cell stack, contributing to the cells declining electricity output, says an article in the March issue of "energy & environment", the newsletter of the MIT Laboratory for Energy and the Environment.
