The beneficial effects have been seen to be particularly beneficial when used in conjunction with gasification in accordance with the invention. It will be appreciated by those skilled in the art that this is contrary to the accepted understanding that whilst serial flow fuel cells, operating at successively lower voltages, will increase the electrical efficiency, the overall power density, and thereby cost per kW of power generated, will be reduced.
