Why Risk Your Fuel Cell Investment? Protect your fuel cell investment by adding the H2S Fuel Cell Protection Filter (a microfibrous media technology) inline filter to the fuel cell's hydrogen supply!

PEM fuel cells must use ultra high purity hydrogen to function at peak efficiency and achieve maximum useful life. Leading fuel cell manufacturers recommend using hydrogen with a purity of 99.99% or greater to realize these goals. Unfortunately hydrogen is "sold separately" and there are few means of ensuring that your fuel source is free from contaminants. A contaminated hydrogen fuel stream can do serious damage to the fuel cell in a short period of time and make waste of your investment without your knowledge. Hydrogen sulfide or H2S is a common contaminant in industrial hydrogen that poisons the fuel cell anode catalyst. Since this poisoning mechanism is irreversible, even trace concentrations of H2S in your hydrogen can over time significantly degrade stack performance. This hydrogen sulfide filter is a simple, easy-to-install filter that operates effectively at low temperatures using its own patented and highly efficient microfibrous absorption media technology. Simply place this filter inline between your hydrogen source and your fuel cell to get the necessary protection you need!
