NOVELTY - A plasma catalyzed thermally integrated reformer comprises channel conveying preheated reactants, plasma generator, reaction zone, and heat transfer mechanism. The plasma generator applies an electrical potential to the reactants to ionize portion(s) of the reactants. The reactants comprise a feedstock fuel and an oxidant. The reaction zone chemically transforms the ionized reactants into synthesis gas. The synthesis gas comprises mixture of hydrogen and carbon monoxide.    USE - The reformer is used for reforming liquid fuels for use in fuel cell systems (200), e.g. solid oxide fuel cell, molten carbonate fuel cells, or phosphoric acid fuel cells used to generate electricity and heat.    ADVANTAGE - The reformer is capable of reforming fuels with high sulfur content, e.g. 10000 parts per million without requiring sulfur pre-removal, while avoiding problems, e.g. poisoning catalyst or carbon buildup. The reformer provides improves overall efficiency of fuel reformation and electricity production. The reformer provides increased Faradaic efficiency of fuel cell.    DETAILED DESCRIPTION - A plasma catalyzed thermally integrated reformer comprises channel conveying preheated reactants, plasma generator, reaction zone, and heat transfer mechanism. The plasma generator applies an electrical potential to the reactants to ionize portion(s) of the reactants. The reactants comprise a feedstock fuel and an oxidant. The reaction zone chemically transforms the ionized reactants into synthesis gas. The synthesis gas comprises mixture of hydrogen and carbon monoxide. The heat transfer mechanism transfers heat utilized in a reformation reaction from an external heat source to destination(s) from preheated reactants, the plasma generator, and the reaction zone. The feedstock fuel comprises fuel, e.g. gas, a liquid, and a solid. The temperature of reformation is 350-1100degreesC. The reformer includes co-axial inner zone containing the plasma generator, and an outer annulus containing the reaction zone, and heating zone to heat the preheated reactants. INDEPENDENT CLAIMS are included for:    (1) thermally integrated system for producing electricity using a feedstock fuel as an input; and    (2) increasing the Faradaic efficiency of a fuel cell.
