Custom Fuel Cell and Electrolyzer Components
Membranes · Catalysts · GDLs · GDEs · MEAs · Bryan, Texas
Membranes, catalysts, gas diffusion layers, gas diffusion electrodes, and membrane electrode assemblies, manufactured in Bryan, Texas.
Specify the reaction, active area, materials, and loading. Fuel Cells Etc makes the materials and builds the component.
What we make
- Membranes and ionomers, including non-standard chemistry, thickness, size, and die-cut shape
- Catalysts, including precious-metal, non-precious, alloy, oxide, carbon-supported, and atypical or mixed compositions
- Gas diffusion layers, made for the electrode and the test
- Gas diffusion electrodes, catalyst-coated to a specified loading
- Catalyst-coated membranes and membrane electrode assemblies: single-sided and double-sided coatings, 3-layer catalyst-coated membranes, 5-layer membrane electrode assemblies, and 7-layer assemblies with custom gasketing
Electrochemical applications
PEM and high-temperature PEM fuel cells, hydrogen-air and hydrogen-oxygen cells, direct methanol and direct ethanol fuel cells, and formic acid oxidation. PEM, anion-exchange-membrane, and alkaline water electrolysis, and unitized regenerative fuel cells. CO₂ electrolysis, with silver for carbon monoxide and copper for methane, ethylene, and ethanol. The anode catalyst is selected separately.
Selected materials are also used for nitrate reduction, electrochemical hydrogen pumps, metal-air air electrodes, chlor-alkali and oxygen-depolarized-cathode work, urea oxidation, electrochemical sensors, and supercapacitor electrodes. For these, we supply the catalyst, membrane, electrode, or assembly. Not the finished industrial system.
Other uses
Selected catalyst powders are used in hydrogenation, CO₂ methanation studies, and other chemical catalysis. Oxidized carbon is used as a catalyst support and as a conductive additive. Suitability depends on the composition and the support.
Test hardware
Test fixtures, vacuum tables, and cell-voltage monitoring can be added to the same order.
For a build that is not a standard configuration, request a quote. Include the reaction or application, active area, membrane, catalyst, loading, and quantity. You do not need the full electrode design before you write.
