Definitions for "PEMFC"
Proton Exchange Membrane Fuel Cell. A PEM is a thin, plastic-like film that facilitates the transport of hydrogen ions from anode to cathode. Several automobile manufacturers have built prototype fuel cell cars that depend on PEM technology. Also known as Polymer Electrolyte Membrane.
Polymer Electrolyte Membrane Fuel Cell
A hydrogen-fueled fuel cell that contains a solid Polymer Electrolyte Membrane (or, equivalently, a Proton Exchange Membrane). Combines hydrogen and oxygen electrochemically to produce electricity, water, and heat.
