This is the most basic operational form of the PEM fuel cell. It consists of the two metal current collector plates on either end, two flow field graphite plates on the inside of those, carbon paper further inside, platinum on the inside of that and the Nafion™ based membrane electrode assembly (MEA) in the middle. All the fuel cell requires to generate electricity is hydrogen and oxygen gas.
We now provide you with ElectroChems single cell fuel cells combining our durable fuel cell hardware with our MEA. Performance curves are provided for use with H2 and O2. Standard MEA specifications: 1 mg/cm² 20 wt% Pt/C loading w/ Nafion™ 115. Custom specifications are available. A reference electrode is provided in the EFC-05-REF and EFC-25-02-REF unit. It consists of a high purity platinum wire inserted into the anode flow field so that it is in direct contact with the input hydrogen gas stream.
Individual electrode potentials can be directly measured relative to this reference electrode to allow researchers to identify individual electrode characteristics using a high impedance potentiometer.
