Determination of optimum electrolyte composition for molten carbonate fuel cells

Description: The goal of this program is the development of a molten carbonate fuel cell (MCFC) anode which is more tolerant of sulfur contaminants in the fuel than the current state-of-the-art nickel-based anode structures. This program addresses two different but related aspects of the sulfur contamination problem. The primary aspect is concerned with the development of a sulfur tolerant electrocatalyst for the fuel oxidation reaction. A secondary issue is the development of a sulfur tolerant water-gas-sh… more

Description: An initial analysis of particulate effects on molten carbonate fuel cells has been conducted. The analysis has been applied to a conceptual fuel cell with operating parameters appropriate to use with future power generation plants. Particle transport due to several mechanisms has been considered and dominant mechanisms affecting particle delivery to anode channel surfaces and into anode pores have been identified. Thermophoresis and gas flow out from anode pores have been found to inhibit parti… more

Development and testing of regenerable hot-coal-gas desulfurization sorbents

Description: Investigations over several years at the Morgantown Energy Technology Center have been concerned with the development of a regenerable metal oxide desulfurization sorbent which would function on hot coal-derived fuel gas. In the latest phase of testing, a combination of zinc oxide with iron oxide as zinc ferrite has produced a sorbent which has demonstrated regenerability and capability of removing sulfur from simulated hot coal gas to a level of 1 to 10 ppM by volume. The principal finding at … more
