Elcogen manufactures solid oxide (SOC) fuel cells and complete solid oxide stack modules called elcoStack. These modules consist of a compression system, gas manifolds and air distribution structure. Solid oxide fuel cells produce electricity and heat (a byproduct) through an electrochemical process from hydrogen or hydrogen-containing fuel. Modules for one and four stacks are available. The company provides a full range of services, from design to on-site project support. Elcogen also creates solid oxide electrolytic cells that produce hydrogen through an electrochemical process from water and electricity. Their electrolysis system includes various components for steam and hydrogen distribution, thermal management, energy conversion, control and more.
