PEM fuel cell hardware provides the structure, gas flow channels, and current collection components of the fuel cell. It holds the membrane electrode assembly in place. Researchers use this hardware to test the performance of their own membranes, electrodes, catalysts, etc.
ElectroChems fuel cell hardware is designed for ease of use and many years of service. Membrane electrode assemblies (ordered separately) are held in place between graphite cell blocks. Flow fields machined into the blocks allow for flow of reactants and provide excellent electrical contact.
Special, low porosity graphite, high purity graphite is used to guarantee a gas tight seal. Current is collected by connection to gold-plated copper contact plates. Separate voltage connectors are provided directly in each cell block for maximum accuracy in iR measurement. Each unit includes resistive heaters and thermocouple wells for accurate temperature control.
