Description

pulled from site's meta description

Borit is a world-class manufacturer of hydroformed high precisionsheet metal products and assemblies. Borit is a full service partner supporting our customers through the full cycle, from conceptual product design, over prototyping to large production series. The innovative Borit Hydrogate technology guarantees optimal product design possibilities, the best product quality, combined with a very high productivity. Products: Flow plates: high precision embossed plates for clean energy applications such as fuel cells, electrolyzers, heat exchangers and solar collectors. Structural panels: full-metal solutions combining light weight with high strength and stiffness, with proven benefits for end-use in transportation, construction, furniture and packaging, amongst others. Borit NV is a spin off company of OCAS NV and borit Leichtbau-Technik GmbH. OCAS is a world leading innovation center for steel solutions, established in 1991 and today a joint venture between ArcelorMittal and the Flemish Region. borit Leichtbau-Technik is a German technology development company, active since 2004. Borit's production centre is based in Zelzate, Belgium, with a technology and product development center in Herzogenrath, Germany. A fuel cell is an electrochemical conversion device. It produces electricity from fuel (on the anode side) and an oxidant (on the cathode side), which react in the presence of an electrolyte. The reactants flow into the cell, and the reaction products flow out of it, while the electrolyte remains within it. Fuel cells can operate virtually continuously as long as the necessary flows are maintained. Fuel cells are different from electrochemical cell batteries in that they consume reactant from an external source, which must be replenished; a thermodynamically open system. By contrast, batteries store electrical energy chemically and hence represent a thermodynamically closed system. Many combinations of fuels and oxidants are possible. A hydrogen fuel cell uses hydrogen as its fuel and oxygen (usually from air) as its oxidant. Other fuels include hydrocarbons and alcohols. Other oxidants include chlorine and chlorine dioxide. A fuel cell works by catalysis, separating the component electrons and protons of the reactant fuel, and forcing the electrons to travel through a circuit, hence converting them to electrical power. The catalyst typically comprises a platinum group metal or alloy. Another catalytic process puts the electrons back in, combining them with the protons and oxidant to form waste products (typically simple compounds like water and carbon dioxide). A typical fuel cell produces a voltage from 0.6 V to 0.7 V at full rated load. Voltage decreases as current increases, due to several factors: Activation loss Ohmic loss (voltage drop due to resistance of the cell components and interconnects) Mass transport loss (depletion of reactants at catalyst sites under high loads, causing rapid loss of voltage) To deliver the desired amount of energy, the fuel cells can be combined in series and parallel circuits, where series yields higher voltage, and parallel allows a stronger current to be drawn. Such a design is called a fuel cell stack. Further, the cell surface area can be increased, to allow stronger current from each cell. Proton exchange fuel cells In the archetypal hydrogen oxygen proton exchange membrane fuel cell (PEMFC) design, a proton-conducting polymer membrane, (the electrolyte), separates the anode and cathode sides.
