Hydrogen Air MEA (3 and 5 layer)

Membrane Electrode Assembly (MEA) for use in Hydrogen/Air Fuel Cells. One of the most economical and cost effective MEAs on the market, the standard configuration features a Platinum loading (0.5 mg/cm²) on a 0.002” membrane. This MEA can be purchased with or without a 410 micron thick woven carbon cloth GDL. Custom sizes and configurations are also available with no minimum order quantities

Platinum on Carbon Catalysts

The ability to prepare well dispersed, high surface area electrocatalysts containing platinum has significantly increased the viability of many electrochemical processes. This new process provides an outstanding, high purity catalyst that is amenable to forming highly uniform electrode structures. Platinum on Carbon (Vulcan, Ketjenblack) is most commonly used for Polymer Electrolyte Fuel Cell (PEMFC), Direct Methanol Fuel Cell (DMFC), Microbial Fuel Cell (MFC), and Phosphoric Acid Fuel Cell (PAFC) applications (as the cathode catalyst or anode catalyst). It is also used as a recombination catalyst for hydrogen elimination. Platinum on Vulcan can also be used as a building block for sensor elements.

Carbon Powders

Carbon powders find their use for various applications such as support for catalyst materials, microporous layer fabrication, electrically-conductive dispersant for ultra-low catalyst loading, conductive filler, etc. Fuel Cell Store team supplies the following carbon based powder materials: Carbon Black - Vulcan XC72 (bead form), Carbon Black - Vulcan XC 72R (fine powder form), Ketjenblack EC-300J, Ketjenblack EC-600JD, graphite, graphene, etc. that can be used in your project applications.

The Fuel Cell Store proudly carries the largest selection of carbon based Gas Diffusion Layers (GDL) in the world! AvCarb, Sigracet, Freudenberg, ELAT, Panex and more. Choose from a large variety of carbon cloths, paper and felts to fit your specific application needs.

PFSA Dispersion

Dispersions (also called ionomers) are one of the critical components of fuel cell components. Catalyst layers require improved ionic conductivity for their optimal operation and hence, preparation of catalyst slurries with the correct dispersion materials will enable high performances. Dispersion (or ionomers) also act as binder agents such as securing the catalyst particles either on the surface of the gas diffusion layers or on the surface of the membranes. During the evaporation of the catalyst ink solvents, a microporous structure is left behind and this helps to bring gaseous or liquid reactants to the catalyst layer or it facilitates the removal of generated gaseous by-products away from the catalyst layer.
