H2S Fuel Cell Sorbent Filter

Protect your fuel cell investment with microfibrous media technology by adding this inline filter to the fuel cell's hydrogen supply

H2S Fuel Cell Filter


Product Description

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 because hydrogen sulfide (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 significantly degrade stack performance over time. IntraMicron's hydrogen sulfide filter is a simple, easy-to-install filter that operates effectively at low temperature using our own patented and highly efficient microfibrous sorption media technology. Simply place this filter between the hydrogen source and fuel cell to maintain protection.
