    摘要: A fuel cell system including: a reformer to convert a fuel into hydrogen; a reformer chamber to contain air heated by the reformer; a fuel cell stack to convert the hydrogen into electricity; a first pump to supply an oxidant to the stack; and a second pump to supply the heated air to the stack, to preheat the stack. The system may also include a controller to control the operation of the system, such that the heated air is not supplied until it reaches a predetermined temperature, and the oxidant is not supplied and the stack is not operated, until the stack reaches a predetermined temperature.

    摘要: A filtering face mask 10 that has a harness 14 and a mask body 12. The mask body 12 is structured such that a snug facial fit can be achieved without use of additional components such as an elastomeric face seal, nose foam, or nose clip. The mask body 12 includes a filtering structure 18 and a cup-shaped shaping layer 20 where the latter comprises a closed cell foam layer that has a plurality of fluid permeable openings located in it. The openings occupy at least 30% of the total surface area of the shaping layer, including a mid region of the shaping layer. The filtering structure is coextensively disposed over the shaping layer. The shaping layer 20 makes contact with the wearer's face at the mask body perimeter 19 when the respirator is being worn. Despite the open nature of the foam shaping layer over much of its surface area, the use of a foam shaping layer, in conjunction with a coextensive filtering structure, provides sufficient structural integrity or stiffness to prevent mask body collapse during respirator use while also exhibiting a low pressure drop to allow for low breathing resistance and extended wearer comfort.

    摘要: Negative active materials for rechargeable lithium batteries, manufacturing methods thereof, and rechargeable lithium batteries including the negative active materials are provided. The negative active material includes a compound represented by the Formula Li1+xV1-x-yMyO2+z. In one embodiment, the compound has an average particle size ranging from about 50 nm to about 30 μm. In another embodiment, the negative active material has a ratio of (003) plane diffraction intensity to (104) plane diffraction intensity ranging from about 1:1 to about 1:0.01 when measured using a Cu K α X-ray. According to another embodiment, after five charge/discharge cycles performed at 0.5C, a specific surface area of the negative active material increases to less than about 20 times a specific surface area before the five charge/discharge cycles. The negative active materials may improve battery capacity, and cycle-life characteristics.
