    摘要： A membrane electrode assembly for an organic/air fuel cell is provided comprising a proton exchange membrane, an anode electrode, and a cathode electrode. The proton exchange membrane is made of a highly fluorinated ion-exchange polymer. The anode electrode is comprised of an anode electrocatalyst of platinum and ruthenium supported on particulate carbon and a highly fluorinated ion-exchange polymer binder, and the metal loading in the anode electrode is less than 3 mg/cm2. The cathode electrode is comprised of a cathode electrocatalyst of platinum supported on particulate carbon and a highly fluorinated ion-exchange polymer binder, and the metal loading in the cathode electrode is less than 3 mg/cm2. Organic/air fuel cells comprised of such membrane electrode assemblies are also provided. A process for operating such membrane electrode assemblies of an organic/air fuel cell is also provided.

    摘要： A culture cup for sampling and microbial-count determination, comprising a body and a tightly closing removable lid, the bottom of the body being provided with depressions for accomodation of at least one culture medium. The lid on its underside may be provided with a recess for accommodation of a condensate absorbent, and the body of the cup with a shoulder to serve as a seat for the bottom of the lid. The lid and body are threaded for engagement. By placing a culture medium in the depression, a biological specimen such as urine or blood can be added in just sufficient quantity to wet the culture so pouring and handling are reduced. Culture and analysis can then be undertaken in the usual manner using the cup body as the carrier of the culture medium.

    摘要： Disclosed is a novel fluid flow field plate for use in a solid polymer electrolyte fuel cell. The flow field plate is made of a suitable electrically conducting material and comprises a substantially planar surface, a flow field formed in said substantially planar surface, said flow field comprising a plurality of staggered lands defining a network of substantially symmetric interconnected orifices and diagonal channels in the flow field and a fluid supply manifold through which fuel and an oxidant are introduced to the flow field and a fluid exhaust manifold through which reaction by-products and excess fuel and oxidant are removed from the flow field. Streams of the fuel, oxidant and reaction by-products are continually separated and diverted into separate channels, and the separated streams are then mixed with streams from adjacent channels in the orfices.

    摘要： A modular unitized electrochemical fuel cell cartridge (20) is formed from a mono-polar anode plate (22), a second mono-polar cathode plate (24 ) and a solid polymer membrane electrode assembly (26) operably interposed between the anode and the cathode. An electrochemical fuel cell stack is provided having at least one removable fuel cell cartridge, a pair of current collectors which are individually disposed on opposite sides of the anode and the cathode plates and a pair of end plates which are individually disposed on opposite sides of the current collectors from the anode and cathode plates. Sealing ridges (42) and mating grooves (44) as well as alignment means (46) enable the easy assembly of a modular unitized fuel cell cartridge and stacking said cartridge.
