Hydrogen fuel cell backup/emergency power source hydrogen refueling System The Hydrogen refueling system manufactured by Beijing CEI Technology Co., Ltd. (short for â??BJ CEIâ?�) are configured with PEM electrolyzers which can delivery hydrogen with purity up to 99.999%.This system will generate hydrogen on site and the product hydrogen will then be compressed to 15-35 Mpa for storage. The system can refuel the fuel cell with power of 5KW, 30KW, 60KW, 100kW, etc. The system has quick response, high integration, small dimension and it runs fully automatically. In the application of hydrogen as an energy storage medium for fuel cell backup power supply, BJ CEIâ??s hydrogen refueling system generates hydrogen when there is electricity (from grid or from wind farm, PV) and will generate electricity immediately when external power supply fails. The hydrogenation unit of BEIJING CEI supporting fuel cell can provide a strong guarantee for field base station, temporary power supply, remote mountain regions power supply, and island power supply, military armament drills, etc., and has opened up the role and value of fuel cells in more areas. BJ CEIâ??s hydrogen refueling system together with fuel cells can provide a very strong temporary power supply proposal for field base station, temporary power supply, undeveloped mountain regions, isolated islands, military exercises. This proposal enables more fuel cell applications in more areas. If solar energy or wind energy is used to generate and store hydrogen, this proposal can provide power supply for partial area or one building. Product Functions Possible use frequency and required power should be taken into consideration for the fuel cellâ??s application as backup power supply. Storage pressureï¼?15Mpa/35Mpa Storage volumeï¼?3.5L, 9L, 12L, 20L, 40L Hydrogen purityï¼?99.999% Hydrogen production capacityï¼?3Lmin-1Nm3/H Product advantages 1.The system is of unattended design.

Zinc Stearate. Zinc Stearate is a zinc soap known for repelling water and is used in the cosmetics and personal care industries as a lubricant. It is an insoluble salt made of commercial stearic acid, a mild fatty acid used as an emollient and lubricant, and is often combined with zinc oxide. Zinc stearate is a â??zinc soapâ?? that is widely used industrially. In this context, soap is used in its formal sense, a metal salt of fatty acid: in this case stearic acid. It is a white solid that repels water. It is insoluble in polar solvents such as alcohol and ether but soluble in aromatic hydrocarbons (e.g., benzene) and chlorinated hydrocarbons when heated. It is the most powerful mold release agent among all metal soaps. It contains no electrolytes and has a hydrophobic effect. Its main application areas are the plastics and rubber industry, where it is used as a releasing agent and lubricant which can be easily incorporated. Zinc Stearate is formed by combining Stearic Acid & Zinc Oxide, the latter of which is an organic white powder compound with a slight characteristic odor. It is insoluble in water, ethyl alcohol & diethyl ether & soluble in acids. In comparison to other metallic stearate, zinc stearate has a low melting point (120 degree C), so it spreads very evenly when heated. Uses and Application of Zinc Stearate- Act as an anti-caking Agent in powdered cosmetics. Act as a lubricant & thickening Agent used to improve texture.. Zinc Stearate is used in plastics and rubber industries, where it is used as a lubricant & release or powdering agent. It functions as an acid scavenger & processes acid in certain Polyolefin applications. It serves as a lubricant acid in sanding sealers and as a flattening agent in paints and coatings. In construction, it is utilized as hydrophobic agents for plasters. In pharmaceuticals & nutraceuticals, it facilitates mould release for tabulating.
