Fuel cell system with premixing of water miscible hydrocarbon fuel and water.

摘要

A fuel cell system employing a reformer for developing a fuel process gas from a hydrocarbon fuel-water mixture wherein the mixture is generated by exclusively delivering a water miscible hydrocarbon fuel to a mixing tank when the level of constituents in the mixing tank falls below a first predetermined level, ceasing delivery of the fuel and initiating exclusive delivery of water to the mixing tank when the level of constituents in the mixing tank rises to a second predetermined level, ceasing delivery of water when the constituents in the mixing tank rise to a third predetermined level, with the level in the mixing tank at the third predetermined level, delivering the hydrocarbon fuel-water mixture to a holding tank when the hydrocarbon fuel-water mixture in the holding tank falls below a first predetermined position, and ceasing delivery of the mixture to the holding tank when the level of constituents in the mixing tank falls below said first predetermined level.
