摘要： A fuel cell design for use at low pressure. The invention has a reduced number of component parts to reduce fabrication costs, as well as a simpler design that permits the size of the system to be reduced at the same time as performance is being improved. In the present design, an adjacent anode and cathode pair are fabricated using a common conductive element, with that conductive element serving to conduct the current from one cell to the adjacent one. This produces a small and simple system suitable for operating with gas fuels or alternatively directly with liquid fuels, such as methanol, dimethoxymethane, or trimethoxymethane. The use of these liquid fuels permits the storage of more energy in less volume while at the same time eliminating the need for handling compressed gases which further simplifies the fuel cell system. The electrical power output of the design of this invention can be further increased by adding a passage for cooling the stack through contact with a coolant. In particular the invention relates to a low pressure gas electrode, comprising an electrically conducting substrate wherein the substrate comprises at least two opposite faces; a plurality of openings allowing passage from one face to an opposite face, wherein the openings encompass between about 10% and about 90% of the total area of the substrate and an electrically conductive porous material bound to the substrate comprised of a electrically conductive component and a binding component.

摘要： The invention provides for reducing the number of parts and the number of interfaces found in certain types of chemical reactors, particularly in electrochemical reactors, and especially in the type or reactor known as a fuel cell or fuel cell stack. This reduction comes from the use of a unified structure that combines the functions normally carried out by several components in the unit, particularly by combining the functions of the gas distribution structure and the gas diffusion structure, the gas distribution structure and the gas barrier structure, or all three structures into a single, unitary, metallic part. This offers the advantages of simplified design, better performance, and lighter weight.

摘要： The invention provides a method for preparing subassemblies for an electrochemical cell or a stack of electrochemical cells, particularly a stack of fuel cells for the direct generation of electricity. The method includes bonding together two or more electrochemical cell components, such as plates, frames, flow fields, shims, gaskets, membranes and the like, to form subassemblies used to make an electrochemical cell stack. The bonding can be accomplished using either polymeric bonds (i.e., adhesives) where polymer and/or metal components are involved or mettalurgical bonds (i.e., solder) where metal components are involved. The bonding provides tightly sealed cells and lower electronic contact resistances between components.

摘要： The present invention provides electronically conducting polymer films formed from photosensitive formulations of pyrrole and an electron acceptor that have been selectively exposed to UV light, laser light, or electron beams. The formulations may include photoinitiators, flexibilizers, solvents and the like. These formulations can be used to manufacture multichip modules on typical multichip module substrates, such as alumina, fiberglass epoxy, silicon and polyimide. The formulations and methods of the invention enable the formation of passive electronic circuit elements such as resistors, capacitors and inductors in multichip modules or printed wiring boards.
