Fuel Cell Components

Browse through the largest collection of fuel cell materials and components in the world at the Fuel Cell Store!

From catalyst to membranes, gas diffusion layers to catalyzed electrodes, catalyst coated membranes (CCMs) to membrane electrode assemblies (MEAs), gasket and bipolar plates to fuel cell stack installation parts, we have every fuel cell component and fuel cell material you could possibly ever need, here at the Fuel Cell Store. 

We offer high performance catalysts in various weight percentages for supported catalysts or in pure metallic or metal oxide forms (with an inventory of 80+ different kinds), have 100+ gas diffusion layer options from an array of vendors around the world, and have offer the largest inventory of ionic membranes (cation exchange membranes, anion exchange membranes, and bipolar membranes). Our gas diffusion electrodes (GDEs, which are also known as catalyzed electrodes), fully assembled membrane electrode assemblies (MEAs), catalyst coated membranes (CCMS) and partial CCMs are all manufactured in our production facility in College Station, Texas with the highest quality available in the market. Fuel Cell Store has the largest variety of cation exchange membranes, anion exchange membranes, and bipolar membrane in the market for fuel cell, electrolyzer, sensors, batteries, chlor-alkali and various other electrochemical applications.  Also offered are dispersions, gasketing, graphite plates, wires and cables, as well as tubing.
