Associating system requests with SMS user responses
A messaging system can initiate a communication with one or more users through via cell phone text messages, for example using the short message service protocol.

Fuel cell system and control method of fuel cell system
In a fuel cell system which executes a stop process of stopping an output from a fuel cell when a required power generation amount for the fuel cell is smaller than a predetermined power generation amount and supplies oxidant during a stop process period, fuel gas is intermittently supplied to a fuel electrode at a basic supply interval, which is set in advance and at which carbon dioxide is not generated in an oxidant electrode, during the stop process period. |

Self-pumping membraneless fuel cell
The present invention is directed to a device, and method of operation, for a fuel cell which uses bubble-based pumping to self-pump the fuel to the anode, and a single, common channel separating the anode from the cathode through which a mixed fuel and electrolyte flow. The fuel cell includes a single channel having two of its sides formed by the anode and the cathode, each having a suitable catalyst. A bubble generating region is formed in the anode and cathode reaction area of the channel. A one-way valve is located upstream of the bubble generating region. A vent for venting bubbles is disposed over a portion of the channel downstream of the bubble generating region. The fuel cell may be advantageously used to build miniature fuel cells for miniature electronic devices, or scaled to build larger fuel cells for larger electronic devices. |

Supported Ni—M materials for electrooxidation of hydrazine
A supported bi-metallic non-platinum catalyst that is capable of oxidizing hydrazine to produce, as by-products of energy production, nitrogen, water, and zero or near-zero levels of ammonia is described. The catalyst is suitable for use in fuel cells, particularly those that utilizes an anion-exchange membrane and a liquid fuel such as hydrazine. |

Secondary battery and method for manufacturing secondary battery
A secondary battery has an electrode laminated body and a collector member. The laminated body is formed of a laminated electrode sheet. The collector member is bonded to a collector foil laminated portion of the electrode sheet not formed with an active material layer. The collector foil laminated portion and the collector member are bonded at overlapped portions by resistance welding using electrodes. When a pressure welding direction is a projection direction, an area ratio (Yd)/(Xd) is 1.2-4, in which Xd is a projection area of a surface of the electrode made contact with the collector foil laminated portion and Yd is a projection area of a surface of the electrode made contact with the collector member. |

Multilayer conductive film, current collector using same, battery and bipolar battery
A multilayer conductive film includes a layer 1 including a conductive material containing a polymer material 1 having an alicyclic structure and conductive particles 1 and a layer 2 including a material having durability against positive electrode potential. The multilayer conductive film has stability in an equilibrium potential environment in a negative electrode and stability in an equilibrium potential environment in a positive electrode, has low electric resistance per unit area in the thickness direction, and has excellent barrier properties for a solvent of an electrolytic solution. A battery including a current collector employing the multilayer conductive film can achieve both weight reduction and durability. |

Anode for lithium secondary battery, method for manufacturing same, and lithium secondary battery including same
Disclosed is an anode for a lithium secondary battery, including a carbon-based anode active material, a binder and a conductive polymer, wherein the conductive polymer is in fiber form. A lithium secondary battery including the anode is also provided. As the anode for a lithium secondary battery includes a conductive polymer in fiber form, poor conductivity, which is a problem with a carbon-based anode active material, can be overcome, and the anode can be easily manufactured. |
