摘要:
Ruthenium or a Ruthenium compound is applied to an anode structure according to a predetermined pattern, with only part of the anode active area containing Ru. The parts of the MEA that do not contain Ru are not expected to suffer degradation from Ru cross-over, so that overall degradation of the cell will be diminished. Having less precious metals will also translate into less cost.

Use of noble metal alloy catalysts, such as PtCo, as the cathode catalyst in solid polymer electrolyte fuel cells can provide enhanced performance at low current densities over that obtained from the noble metal itself. Unfortunately, the performance at high current densities has been relatively poor. However, using a specific bilayer cathode construction, in which a noble metal/non-noble metal alloy layer is located adjacent the cathode gas diffusion layer and a noble metal layer is located adjacent the membrane electrolyte, can provide superior performance at all current densities.

摘要:
A latch device including a latch strike retention assembly adapted for press-fit insertion into a panel opening and retention within the panel opening upon melting of any plastic components. The latch strike retention assembly includes a generally “U” shaped spring member having spring legs operatively connected to bushings arranged in converging opposing relation to one another and adapted to engage and retain a strike member disposed in opposing relation to the strike retention assembly. The spring member is held within a bracket member of substantially “U” shaped cross section. The bracket member is disposed in transverse orientation to the spring member.
摘要:
A transverse-wave logging tool consists of a plurality of sets of transducers mounted around a cylindrical mandrel. The transducer active faces are characterized by two orthogonal dimensions, one of which dimensions is a half-wavelength long relative to the acoustic excitation energy applied to a transmitter transducer and the transverse-wave formation velocity. Receiver transducers detect converted-compressional waves resulting from transverse waves that were generated by the acoustic excitation energy.
摘要:
A suspended containment wall system including a support rail with a hook track positioned thereon and a hanging panel. The hanging panel further includes: (i) an attachment rail with a hook track oriented to engage the hook track of the support rail; and (ii) a panel body connected to the attachment rail.
摘要:
A control system (106) for mounting to a vehicle (100) and for providing information to an occupant of the vehicle from a first source device (116) is provided. The vehicle includes an audio system (130) and/or a display system (100). The control system includes a first interface (120) for communicating with the first source device (116). The control system further includes a second interface for providing a signal to the audio system and/or the display system. The control system yet further includes a processor (122). A memory unit (122) is communicably connected to the processor and includes a first transport (2112) configured to send a control signal to the interface. The memory unit (132) further includes a first manager (2304) configured to receive a command from an application (2104) and to translate the command from the application (2104) into a command for the transport (2112).

摘要:
An air compressor assembly includes a compressor configured to provide a source of compressed air and a manifold assembly removably coupled to the compressor and configured to distribute the compressed air to one or more pneumatic tools. The manifold assembly is configured to be coupled to the compressor via an air conduit when the manifold assembly is detached from the compressor so that the manifold assembly is operable at a location remote from the compressor.
