摘要： A membrane electrode assembly includes an anode; a cathode; a membrane disposed between the anode and the cathode; and an extended catalyzed layer between the membrane and at least one electrode of the anode and the cathode. The extended catalyzed layer includes catalyst particles embedded in membrane material and preferably includes a first plurality of particles which are electrically connected to the at least one electrode. The extended catalyzed layer may further preferably have a second plurality of particles which are electrically disconnected from the at least one electrode.

摘要： A method for making a membrane electrode assembly includes the steps of providing a membrane electrode assembly including an anode including a hydrogen oxidation catalyst; a cathode; a membrane disposed between the anode and the cathode; and depositing a peroxide decomposition catalyst in at least one position selected from the group consisting of the anode, the cathode, a layer between the anode and the membrane and a layer between the cathode and the membrane wherein the peroxide decomposition catalyst has selectivity when exposed to hydrogen peroxide toward reactions which form benign products from the hydrogen peroxide. The peroxide decomposition catalyst can also be positioned within the membrane. Also disclosed is a power-generating fuel cell system including such a membrane electrode assembly, and a process for operating such a fuel cell system.

摘要： The invention is a fuel cell (20) having a corrosion resistant and protected cathode catalyst layer (24). The cathode catalyst layer (24) includes a platinum oxygen reduction catalyst and an oxygen evolution catalyst selected from the group consisting of catalysts that are more active than platinum for oxygen evolution. The oxygen evolution catalyst may be uniformly applied within the cathode catalyst layer, or non-uniformly applied to identified high corrosion areas (82) (84) of the cathode catalyst layer (24). The cathode catalyst layer (24) may include heat-treated carbon support material, and/or a heat-treated carbon black within a diffusion layer (40) supporting the cathode catalyst layer (24). The fuel cell (20) may also include an anode catalyst layer (22) having a poor oxygen reduction catalyst having a greater oxygen reduction over potential than platinum.

摘要： Solid polymer membrane fuel cell water which collects on the oxidant side of the membrane is removed from the active area of the cells in a fuel cell power plant by being absorbed into porous carbon bodies, one of which contacts the membrane. Some of the treated carbon bodies can also be used to supply water to the anode side of the membrane in order to minimize anode side membrane drying. The pores in the carbon body are partially filled, or coated, with precursors of metal oxyhydroxide compounds, which, when converted, will impart increased wettability and water absorption capacity to the carbon body. Hydroxides of the filler compounds are applied to the carbon body and are heated to convert them into oxyhydroxides. As used in this document, the term "oxyhydroxide" includes oxyhydroxides, oxyhydroxide hydrates, and oxide hydrates. Processing temperatures are low enough so as to not subject the bodies being impregnated to destabilization.

摘要： In a near ambient pressure operated auto-thermal reformer fuel gas system, a precooler between the auto-thermal reformer and shift converter. The precooler includes a spraying water inlet, an inlet for the reformed gas and a packing of high surface area material which increases the available surface area for water evaporation in the precooler so as to effectively cool the hot reformed gas.
