摘要:
An interlocking isolator for a proton exchange membrane fuel cell is provided which protects a fuel cell positioned in the interlocking isolator from electricity and heat. The interlocking isolator also permits multiple fuel cells positioned with the isolators to be stacked adjacently, thereby forming fuel cell stacks.
摘要:
A fuel cell stack (2) constructed and assembled so that a membrane-type humidifying exchanger (1) enables diffusional contact of a re-circulating aqueous liquid fuel supply and the oxidant air stream supplied to the fuel cell stack (2) is provided. The assembly is configured so that the fuel cell stack (2) is mounted together with other ancillaries on a base provided by the membrane-type humidifying exchanger (1).
摘要:
A fuel delivery manifold enlarged in size is provided which, when incorporated into fuel cells which are then stacked allows for insertion of a baffle or a perforated fuel delivery tube through the fuel cell stack via the enlarged fuel delivery manifold to enhance and/or even out or equalize fuel delivery to all fuel cells in the fuel cell stack.
摘要:
Fuel cells equipped with a self-contained gas- or air-lift which circulates fuel through the channels of the separator plate of the fuel cell via gaseous carbon dioxide produced by the reaction of the membrane electrode assembly and the fuel are provided. Also provided are exemplary self-contained gas-or air-lifts useful for production of these fuel cells.

The present invention provides polymeric radio frequency resonant tags and methods of manufacturing these tags for use in detection of theft of article for sale.
摘要:
The present invention provides radio frequency resonant tags and methods of manufacturing these tags for use in detection of theft of article for sale. In these tags, the radio frequency is transmitted through a resonance circuit without the need for direct connection of a conducting pattern or conducting patterns, but rather via a dielectric film which is adjacent to the conducting pattern or separates the conducting patterns.
摘要:
Sensor laminates for detection by immunoassay of target molecules in biological fluids wherein the sensor laminates contain a reactive substrate layer having a polymeric material treated to enhance binding to a ligand and methods of producing and using these sensor laminates are provided. Also provided are multi-sectioned fluid delivery devices for use with the sensor laminates in detection of target molecules in biological fluids.
