    摘要： A high power density direct oxidation fuel cell (DOFC) with comprising an anode electrode with a microporous layer (MPL) configured to alleviate cathode dryout and thus reduce electrode resistance in the cathode that interfaces with a hydrocarbon membrane. The MPL is configured to alleviate cathode dryout by comprising a fluoropolymer and an electrically conductive material, wherein the MPL is loaded with fluoropolymer in the range from about 10 to about 25 wt. %.

    摘要： A ceiling-mount omnidirectional antenna for indoor distribution system of mobile communication network and a method for manufacturing the same are provided. The antenna includes: a monopole consisting of a cone part and a columnar part; a reflecting plate consisting of a cone part and a platform part; and a feed connector. The monopole and the reflecting plate are arranged in such that the tips of cone parts are opposite to each other. The signal is fed into the antenna through the feed connector and radiated outward by the monopole and the reflecting plate. In high frequency band, the maximal gain appears at about 70°, so that the signal power focuses at radiating angles of 60°˜85°. Comparing to the existing antenna, the gain of the antenna increases 4.22 dB at a radiating angle of 85° and decreases 10 dB at a radiating angle of 30°. So, the maximal permissible value of antenna aperture power of mobile communication signal in high frequency band, such as 3G, is increased; and the field strength of signal covering the edge is increased. The antenna can increase the covering range of a single antenna, increase the signal quality, and cover 2G and 3G networks in the same time so as to reduce the difficulty and the cost for building and reconstructing an indoor distribution system in 3G.
