DESCRIPTION
DuPont’s Membrane Electrode Assemblies (MEAs) are available for Direct Methanol (DM) applications in a 3 layer configuration (MEA3), with appropriate Electrodes on each side of optimised Nafion PFSA Membrane. Sandwiched between two pieces of black carbon paper, the Nafion membrane forms the main reaction site. The MEA functions like a simple battery cell. Stacks of MEA are connected by the graphite bipolar plates. A fuel cell stack is a stack of MEA (cell) connected in series with graphite bipolar plates in between. MEA3 is fabricated to specific fuel cell operational and dimensional requirements based on customer’s provided details of the dimensions. GasHub is the authorised dealer for DuPont’s MEAs.
