Fuel cells: Cogeneration of c2 hydrocarbons or simultaneous production/separation of h2 and c2 hydrocarbons

Abstract

Chemicals and energy cogeneration processes have been shown to be a promising alternative to conventional reactors and fuel cells. Solid electrolyte membrane reactors (SEMRs) have been widely studied in fuel cells applied as a chemical reactor. This chapter describes the SEMRs and important catalytic aspects on the oxidative coupling of methane (OCM) to understand how these two technological alternatives can be combined to increase the C2 hydrocarbon yield, cogenerate electric power or produce valuable chemical compounds by using of SEMR in its two main operating modes (fuel cell and O2- ion ‘‘pumping’’ mode).
