摘要:
A solid polymer electrolyte composite membrane and method of manufacturing the same. According to one embodiment, the composite membrane comprises a thin, rigid, dimensionally-stable, non-electrically-conducting support, the support having a plurality of cylindrical, straight-through pores extending perpendicularly between opposing top and bottom surfaces of the support. The pores are unevenly distributed, with some or no pores located along the periphery and more pores located centrally. The pores are completely filled with a solid polymer electrolyte, the solid polymer electrolyte including a dispersed reduced noble metal or noble metal oxide. The solid polymer electrolyte may also be deposited over the top and/or bottom surfaces of the support.

A gas diffusion electrode and method of making the same. According to one embodiment, the electrode comprises a support layer, a first cushioning layer positioned on top of the support layer, a second cushioning layer positioned on top of the first cushioning layer, and a catalyst layer positioned on top of the second cushioning layer. The support layer is a mechanically stable, electrically-conductive, gas porous substrate, such as carbon fiber paper. The first cushioning layer, which is also gas porous, comprises a non-woven mat of electrically-conductive, chemically-inert fibers, preferably carbon nanofibers, bound together with a polymeric binder, such as polytetrafluoroethylene. The second cushioning layer is similar to the first cushioning layer, except that carbon black or a similar electrically-conductive, chemically-inert particulate material is included in addition to or instead of the fibrous material for the purpose of fine-tuning pore size.

A condensing lens, compound-eye lens condenser, and compound-eye concentrating-type solar cell assembly. The condensing lens is a convex lens that can reflect mutually parallel incident lights (3) onto a receiving surface (4) on the outer side of the lens and thus form spots. If the vertical distance from the contact point of any incident lights (3) contacting the lens to a light axis (103) of the lens is x, the vertical distance between a projection point formed from the incident light (3) reflecting onto the receiving surface (4) and the center of the spot is m, the radius of the lens is a, and the radius of the spot is b, then the lens meets the following condition: x/m=a/b. The condensing lens has a high transmission rate, and the energy distribution of the spots is more even after condensing, the transmission rate is 90% to 93%, and the energy distribution curve of the spots transmitted through the condensing lens is similar to saddle-shaped.

摘要:
Electrical devices having a plurality of stacked electrode layers are described. At least one of the electrode layers contains continuous fibers that are infused with carbon nanotubes. The continuous fibers can be disposed upon an electrically conductive base plate. The electrical devices can further contain an electrolyte contacting each electrode layer and a layer of separator material disposed between each electrode layer, in which case the electrical devices can form a supercapacitor. Such supercapacitors can have a capacitance of at least about 1 Farad/gram of continuous fibers. The capacitance can be increased by coating at least a portion of the infused carbon nanotubes with a material such as, for example, a conducting polymer, a main group metal compound, and/or a transition metal compound. Methods for producing the electrical devices are also described.

摘要:
An MEA for a fuel cell that employs multiple catalyst layers to reduce the hydrogen and/or oxygen partial pressure at the membrane so as to reduce the fluoride release rate from the membrane and reduce membrane degradation. An anode side multi-layer catalyst configuration is positioned at the anode side of the MEA membrane. The anode side multi-layer catalyst configuration includes an anode side under layer positioned against the membrane and including a catalyst, an anode side middle layer positioned against the anode side under layer and not including a catalyst and an anode side catalyst layer positioned against the anode side middle layer and opposite to the anode side under layer and including a catalyst, where the amount of catalyst in the anode side catalyst layer is greater than the amount of catalyst in the anode side under layer.

The case cable management has a shell, a circuit board, multiple sockets and a cover. The shell has a bottom board and a sidewall. The circuit board is attached securely to the bottom board of the shell. The sockets are mounted through the sidewall of the shell and have multiple terminals connected securely to the circuit board. The cover covers the shell. Multiple power lines are mounted through the sidewall of the shell to connect the circuit board and sockets to a power supply and cables from computer apparatuses are connected to the sockets to receive electric power. Different cables can be distinguished clearly and conveniently for simplified cable routing to avoid confusion and facilitate replacement.
