  • Patent number: 9356300
    Abstract: A fuel cell stack includes a plurality of fuel cell cassettes each including a fuel cell with an anode and a cathode. Each fuel cell cassette also includes an electrode interconnect adjacent to the anode or the cathode for providing electrical communication between an adjacent fuel cell cassette and the anode or the cathode. The interconnect includes a plurality of electrode interconnect protrusions defining a flow passage along the anode or the cathode for communicating oxidant or fuel to the anode or the cathode. An electrically conductive material is disposed between at least one of the electrode interconnect protrusions and the anode or the cathode in order to provide a stable electrical contact between the electrode interconnect and the anode or cathode. An encapsulating arrangement segregates the electrically conductive material from the flow passage thereby, preventing volatilization of the electrically conductive material in use of the fuel cell stack.

  • Patent number: 8961651
    Abstract: Energy consumption of the society is increasing due to expanding economic activity and increasing population. As greater consumption of energy generates more air pollution, there is an ongoing need to find better methods of reducing pollutants in terms of effectiveness and reduced energy consumption. The solution proposed in this disclosure takes advantage of electrical characteristics such as electron affinity and dipole moment. There are many pollutants which exhibit positive electron affinity. Such a pollutant can be easily converted to a negative ion by providing an extra electron. Many of the pollutants have dipolar charge distributions which facilitate electrical interactions with charges. If one of the pollutants becomes charged, it can attract other pollutants which are dipoles to form clusters of pollutants. Furthermore, charged clusters are responsive to electric and magnetic fields. For example, they can be separated from the rest of the flue gas by manipulating with such fields.

    Abstract: An air purifier includes a frame, a fan unit, and an electrostatic precipitator. The precipitator has a first strip with a first continuous conductive electrode layer directly adjacent to an edge, and a second strip with a second continuous conductive electrode layer directly adjacent to an edge. The first and second strips are nested with one another. The edge of the first strip is opposed to the edge of the second strip. An electrostatic precipitator for an air purifier includes a first spiral strip having a continuous conductive electrode, a second spiral strip having a continuous conductive electrode and nested with the first strip, a plurality of combs. Each comb extends from an outer periphery of the precipitator to an intermediate region between the outer periphery and a center of the precipitator.

  • Publication number: 20130032088
    Abstract: A method and device for separating overspray from the cabin exhaust air of coating systems which is laden with overspray, wherein the overspray is taken up by an air flow and conveyed to an electrostatically operating separating device. There, the bulk at least of the solids is separated from the overspray at a separating area of at least one separating surface. A cohesive material web is used as a separating agent, which is disposed at least partly along the separating area of the at least one separating surface and during operation of the separating device is electrically conductive at least in the separating area of the at least one separating surface.

  • Publication number: 20120312169
    Abstract: The present invention is an air purification method and device. Due to the lower airflow resistance that the present invention induces, an exhaust fan or blower with motor of lower torque is adopted. Consequently, the whole air purification is operated at a lower noise level. Lower operational voltage is applicable for the high-voltage electrostatic precipitator device and provides a similar or superior performance and effectiveness for dust removal. The air purification device/system is designed with higher flexibility and of more compact in dimension and size. Dust is removed from the environment by a high voltage electrostatic precipitator. The airflow stream within a high-voltage electrostatic precipitator is such that the direction of the path of the airflow is changed at least twice.
