HENGKO porous metal gas diffusion layers are the leading choice for high performance electrolyzer and fuel cell applications. The uniform porosity, strength, and corrosion resistance provides superior performance over other di usion layer products. Mott substrates are available in a variety of alloys to support a full range of fuel cell operating temperatures, and can be coated with surface treatments or catalyst layers to enchance performance.
Depth filter sheets are used to remove particles from liquids. This means that liquids can be clear-, fine- or sterile-filtered. Filter sheets are ideal for higher particle load filtration, where mere surface filters such as membranes do not provide enough life-time. With a thickness of 3 – 4 mm, more than 3000 times the size of a 1-micron particle, millions of microparticles can be trapped in every square meter of the filter area. Typically, filter sheets consist of a matrix of cellulosic or polymer fiber, enriched with minerals filter aids and held together with a resin binder.
Depth filter sheets are available in various grades for a wide variety of applications. The filter sheets show nominal retention rates from coarse (55 – 20 μm) to fine (15 – 1 μm) to sterile (0.6 – 0.04 μm). Therefore, they can be used for clarifying, fine and sterile filtration. They are available in all common sizes from 47 mm rounds up to 2.4 m × 1.2 m filter sheets. In between, practically all sizes are possible for all the different sheet filters available on the market.
