摘要： A method for designing a fuel processor (10) having an optimized size (i.e, volume and mass) for use in a fuel cell system which provides electrical power in a plurality of power ranges. The method includes maximizing water availability in the fuel cell system and sizing the first CO reduction reactor (22) to provide for peak fuel cell system operational efficiency in a most-used power range while sizing the second CO reduction reactor (24) to ensure the fuel processor components can operate at a desired maximum power. The method allows development of a fuel processor that has significantly lower total mass and volume, and shorter start-up time, than conventionally designed processors, yet can perform at a desired maximum power.

摘要： A proton exchange membrane fuel cell including a membrane electrode assembly comprising a proton transmissive membrane, a catalytic anode layer on one face of the membrane, and a catalytic cathode layer on the other face of the membrane. The fuel cell further includes a gas distribution layer on each of the cathode and anode layers defining a gas flow field extending over each of the catalytic layers. The membrane electrode assembly has a convoluted configuration whereby to increase the ratio of membrane area to planar fuel cell area and thereby increase the electrical output of the fuel cell for a given planar area size fuel cell. The convoluted configuration of the membrane electrode assembly also facilitates the division of the gas distribution layers into separate parallel channels thereby allowing the use of an inexpensive foam material for the gas distribution layers irrespective of the inherent variations in porosity of foam materials.

摘要： A proton exchange membrane fuel cell comprising a proton transmissive membrane, a catalytic anode layer on one face of the membrane, a catalytic cathode layer on the other face of the membrane, and a gas distribution layer on each of the cathode and anode layers defining a gas flow field extending over each of the catalytic layers. Each of the gas distribution layers comprises a layer of open cell conductive foam material which is divided into a plurality of generally parallel segments extending from one edge of the fuel cell to an opposite edge of the fuel cell whereby to define a plurality of generally parallel porous reactant paths extending across each catalytic layer. The segments may be defined by selectively varying the porosity of the foam material or selectively varying the thickness of the foam material. Reactant gases are delivered to the foam gas distribution layer via a manifold structure in which the reactant gases are moved upwardly along an edge of the fuel cell stack in parallel paths and selectively distributed within the stack at the desired cathode or anode levels by selective baffling and partitioning structures. A coolant layer may also be provided utilizing the same segmented foam construction utilized in the anode and cathode layers. The resultant fuel cell is lighter, smaller, and less expensive than prior art cells having comparable per surface area unit electrical energy output.

摘要： The present invention relates to a separator plate in an electrochemical cell having a body with an electrically conductive first section having fluid flow fields with a plurality of flow channels formed therein and a second section adjacent to the first section that has a header area defining a manifold that supplies fluids to the flow fields of each fuel cell. The second section is non-conductive to prevent possible electrical interaction with any aqueous fluids of finite ionic conductivity present in the fuel cell, which may result in inefficient fuel cell operations. Further, the present invention contemplates methods to form such a separator plate.

摘要： The present invention relates to an electrochemical cell having a terminal collector plate element (10) that conducts electrical current from the stack. The terminal plate (10) has an electrically conductive region (102) and an electrically nonconductive region (100) on the surface. The non-conductive region (100) is coated with a corrosion resistant coating (140) that comprises either a passivation layer, a corrosion-resistant polymeric layer, or both. Optionally, the conductive region of the terminal plate may be protected from oxidation, by coating with an oxidation-resistant metal layer. The oxidationresistant layer may be further coated with a conductive oxidation-resistant polymeric layer. Other preferred aspects of the present invention include methods of treating the terminal plate to resist corrosion and oxidation while still maintaining electrical conductivity.

摘要： A bipolar plate assembly for a proton exchange membrane fuel cell stack advantageously connects electrically conductive plate surfaces, without the requirement to weld or braze the plate pairs. Each plate has alternating coolant channels and lands formed on an inside facing surface. An electrically conductive layer is deposited over at least the coolant channels and lands. Pairs of plates are aligned having facing electrically conductive layers. A fluid seal is disposed between the inside facing surfaces about a perimeter of the coolant channels. Each plate pair is compressed to form a plurality of electrical bond lines between adjacent lands within the perimeter seal. The perimeter seal prevents stack reactant gas oxygen from contacting and oxidizing the electrically conductive layer. A dielectric coolant is also used to reduce oxidation of the electrically conductive layer.

摘要： An optical fiber for use in fiber optic sensing of a test sample includes a first core (16) and a second core (14). The second core (14) is generally coaxially disposed within the first core (16) and is sized smaller than the first core. The second core (14) is capable of delivering pulsed laser energy from the laser (12) for nonlinear optical excitation of the test sample. Nonlinear optical feedback signals can then be collected in both the first core and second core for improved detection efficiency relative to conventional single-mode and multi-mode fibers.
