Precious metals are used in fuel cells to maximise the lifetime of the cell for any given performance requirement. Materials such as molybdenum or nickel are prone to deactivation owing to particle restructuring and the formation of surface adsorbed debris from the fuel component. Precious metals offer significant resistance to these effects - but, precious metals are expensive and it is vitally important for developers and manufacturers to maximise efficiency and yield.

With over 30 years of experience in Catalytic Chemistry, Ceimig has unparalleled expertise in the development and manufacture of high quality HSA (High Surface Area) materials for application in Hydrogen and Ethanol, Proton Exchange Membrane (PEM) Fuel Cells.

We use a proprietary process which avoids sintering and results in materials that exhibit typical surface areas in the range 80 - 100m²/g - up to 10 times the typical surface area of industry standard materials. Surface area and porosity measures fall into a tight statistical distribution - maximising process and performance consistency and reducing waste.

Our customers see consistently ‘sooty’ materials rather than variably sooty and salty materials that are available elsewhere. This ensures that our customers benefit from the best available cost to technical performance ratio, greater cell design flexibility and enhanced process stability.
