  • Patent number: 8871403
    Abstract: A fuel cell stack system is configured to uniformly supply a fuel or an electrolytic solution to each of fuel cell elements, and an electronic device using the fuel cell stack system are provided. An electrolytic solution channel allowing an electrolytic solution to flow therethrough is arranged between a fuel electrode and an oxygen electrode, and a fuel channel allowing a fuel to flow therethrough is arranged outside of the fuel electrode. The electrolytic solution channels and the fuel channels of all fuel cell elements are connected in series to one another. That is, the fuel or the electrolytic solution emitted from an outlet of the fuel channel or the electrolytic solution channel of one fuel cell element enters into an inlet of the fuel channel or the electrolytic solution channel of the next fuel cell element through a connection channel.

  • Patent number: 8858432
    Abstract: Ingestible event marker systems that include an ingestible event marker (i.e., an IEM) and a personal signal receiver are provided. Embodiments of the IEM include an identifier, which may or may not be present in a physiologically acceptable carrier. The identifier is characterized by being activated upon contact with a target internal physiological site of a body, such as digestive tract internal target site. The personal signal receiver is configured to be associated with a physiological location, e.g., inside of or on the body, and to receive a signal the IEM. During use, the IEM broadcasts a signal which is received by the personal signal receiver.

  • Publication number: 20140302422
    Abstract: Magnesium energy storage devices that take advantage of magnesium-based anodes while maintaining practical energy densities can be useful for large-scale energy storage as well as other applications. One such device can include a negative electrode having magnesium and a positive electrode material that can flow in a batch or continuous manner. The flowable positive electrode material can result in an increased practical energy density because the fresh active material can be flowed to the positive electrode, and as a result can be theoretically infinite in size. The positive electrode can include a cathode suspension contacting a positive current collector and having particulates of a cathode magnesium intercalation compound, a cathode magnesium conversion compound, a redox active species, or combinations thereof.

    Abstract: A flow battery includes a liquid electrolyte having an electrochemically active specie. A flow field plate includes a first flow field channel and a second flow field channel that is separated from the first flow field channel by a rib. There is a flow path for the liquid electrolyte to flow over the rib between the channels. An electrode is arranged adjacent the flow field plate such that the liquid electrolyte that flows over the rib must flow through the electrode. The electrode includes a carbon paper that is catalytically active with regard to liquid electrolyte. The carbon paper defines a compressive strain of less than 20% at a compressive stress of 0.8 MPa and an uncompressed porosity in the range 60-85%.

    Abstract: Abiotic fuel cell and battery designs employing chemical dyes in alkaline solutions are disclosed. The fuel cells and batteries are capable of harnessing electrical power from various carbohydrates, including, but not limited to, glucose; in an anode design that does not require catalysts or membranes to separate half-cell reaction chambers. In certain embodiments, the abiotic fuel cell or battery designs may further employ electrodes, such as high surface area carbon materials and commercial air breathing electrodes, without the use of catalysts for glucose oxidation (i.e., precious metals or biocatalytic species). In further embodiments, organic dyes, including but not limited to, methyl viologen (MV), methylene blue, methylene green, Meldola's blue, indigo carmine, safranin O, and the like, may serve as the electron mediators. In some embodiments, the fuel cells or batteries are capable of generating power on the order of about tens of mW/cm2 from glucose and/or other types of sugars.
