摘要： A direct organic liquid feed unit fuel cell comprises an anode current collector, a cathode current collector, a membrane electrode assembly, and a fuel delivery layer for diluting a concentrated fuel stream and delivering the fuel stream to the anode at a uniform concentration across the planar extent of the anode, independently of the orientation of the fuel cell.

摘要： A low contaminant formic acid fuel is especially suited toward use in a direct organic liquid fuel cell. A fuel of the invention provides high power output that is maintained for a substantial time and the fuel is substantially non-flammable. Specific contaminants and contaminant levels have been identified as being deleterious to the performance of a formic acid fuel in a fuel cell, and embodiments of the invention provide low contaminant fuels that have improved performance compared to known commercial bulk grade and commercial purified grade formic acid fuels. Preferred embodiment fuels (and fuel cells containing such fuels) including low levels of a combination of key contaminants, including acetic acid, methyl formate, and methanol.

摘要： A method and system for counteracting performance deterioration in an electrochemical fuel cell includes passive re-activation, active re-activation, or both. Active re-activation includes intermittently applying positive voltage electrical pulse across the anode. The positive voltage applied is less than that required for decomposition of water. Passive re-activation includes interposing a resistive load between the anode and the cathode while fuel stream flow to the anode is interrupted. The resistive load increases voltage potential at the anode to less than that required for oxidation of carbon.
