    Abstract: A direct methanol fuel cell unit is provided with a fuel cell including an anode, a cathode with a hydrophobic microporous layer, an electrolyte membrane put in-between, and a fuel supply path supplying fuel to the anode. The fuel supply path is provided with an upwind water barrier preventing back-diffusion of water and a gas flow path channeling gas generated at the anode and disposed between the barrier and the anode. A water-rich zone is formed between the water barrier and the cathode microporous layer. Water loss from either side of this zone is eliminated or minimized, thereby permitting direct use of highly concentrated methanol in the fuel flow path with good fuel efficiency and power performance. The cell unit can be applied equally well to both an active circulating air cathode and an air-breathing cathode.

    Abstract: This invention relates to the field of resin, particularly to a magnetic, acrylic strongly basic anion exchange microsphere resin and its manufacturing method. Its basic structure is as follow: wherein its matrix contains magnetic grains and A is a group containing quaternary ammonium salts; the manufacturing method is: taking acrylic compounds as the monomer and mixing it with the crosslinking agent and porogenic agent to form an oil phase; evenly mixing the oil phase with magnetic grains and then conducting suspension polymerization; aminating and alkylating the polymerized magnetic grains so as to form the quaternary ammonium salts, namely the magnetic, acrylic strongly basic anion exchange microsphere resin. The exchange capacity of this resin is higher than that of any magnetic strongly basic anion exchange microsphere resin available either on both Chinese and overseas markets or in literature; it is able to take the place of the traditional strongly basic anion exchange resin in separating and removing soluble organics, particularly precursors of disinfection by-products, and various anions such as nitrates and phosphates.

    Abstract: A mobile gateway device collects identities of a first set of radio nodes which are within one hop of the mobile gateway; and checks at least the collected identities against a first table and a second table. The first table lists node identities and corresponding data validity timers. The second table lists node identities and no corresponding data validity timers. From the checking the device selects a group of radio nodes to activate for collecting and reporting data. The device determines parent child relations among the radio nodes, which are sensor nodes of a wireless sensing network in an embodiment, and uses the list to activate only those nodes for which it does not have valid data to sense new data and transmit their sensing results.
