Fuel cell is an electrochemical cell that turns chemical energy from a fuel into electric energy. Electricity is produced from the reaction between a fuel supply and an oxidizing agent. The reactants... More > flow into a cell, and the reaction products flow out of it, while the electrolyte stays inside it. Fuel cells can function constantly as long as the required reactant and oxidant flows are maintained. Fuel cells are varied from traditional electrochemical cell batteries in that they consume reactant from an external source which must be replenished as thermodynamically open system.< Less

Business elements include structural and infrastructural elements. Structural elements are tangible resources, such as buildings, equipment, and computer systems. These resources typically require... More > large capital investments that are difficult to reverse. Because of their cost and inflexibility, such elements arc changed infrequently and only after much deliberation. In contrast, infrastructural elements are the people, policies, decision rules, and organizational structure choices made by the firm. These elements are, by definition, not as visible as structural elements, but are just as important. Total quality management (TQM) is a managerial approach in which the entire organization is managed so that it excels in all quality dimensions that are important to customers. Organizations that adopt TQM as one of their infrastructural elements will probably make structural and infrastructural decisions that are very different from those of firms that don’t follow such an approach.< Less
