Abstract: There are provided a pump of a noise suppression and vibration proof structure and a fuel cell system using the same. The fuel cell system includes at least one electricity generator including an electrolyte membrane and an anode and a cathode attached to the both surfaces of the electrolyte membrane to generate electricity energy by the electrochemical reaction between fuel containing hydrogen and oxidant supplied to the anode and the cathode, a fuel supplying unit including a pump for supplying the oxidant to the electricity generator, and a fixed frame that is provided on a lower frame and to which the pump is fixed. The pump is separated from the lower frame and is fixed to and combined with the fixed frame by the belt-shaped fixing member on the side surface of the fixing frame with a buffering member interposed. Therefore, it is possible to reduce the noise and vibration of the pump.

Abstract: A negative electrode is provided. The negative electrode includes a negative electrode current collector, and a negative electrode active material layer formed over the negative electrode current collector, and including a plurality of columnar bodies. An organic material layer having ion conductivity is held by said negative electrode active material layer, said organic material layer is formed at least in an inside of each of said columnar bodies. The active material layer may include silicon.

Abstract: This invention provides an actively controlled battery with a programmed-timing actuation capability. The battery comprises a first electrochemical assembly, at least a second electrochemical cell assembly electronically connected in parallel with the first assembly, and control means in control relation to the first assembly and the second assembly, wherein at least one of the assemblies comprises a metal-air cell comprising a cathode being isolated from outside air through a controllable air vent and at least one of the assemblies comprising an electrochemical cell comprising an anode active material being initially isolated from an electrolyte fluid through a control valve, with both the air vent and control valve being regulated by the control means in a programmed-timing fashion. The battery has an exceptionally long operating life and is particularly useful for powering microelectronic or communication devices such as mobile phones, laptop computers, and palm computers.

Abstract: An alkaline battery includes a cathode, an anode, a separator between the anode and the cathode, and an alkaline electrolyte contacting the anode and the cathode. The separator includes a first generally cylindrical body. The first generally cylindrical body includes a first wall section, a second wall section, and a first folded section. The first folded section is radially outwardly disposed from the first wall section.

Abstract: The present invention relates to a new strategy against the electrolyte migration through the gasket in externally manifolded MCFC stacks. This is obtained by endowing a stack of molten carbonate fuel cells (MCFCs) of an electrolyte management tool separated from the cells by an electronically conductive material which is impervious to gas, characterized by the combination of the following elements:—a positive reservoir component external to the cathode of the first cell on the positive side of the battery, wherein said reservoir consists of one ore more porous layers of electronically conductive material and comprises at least one gas distributor, and—a negative reservoir component external to the anode of the last cell on the negative side of the battery, wherein said reservoir consists of one ore more porous layers of electronically conductive material.

Abstract: A fuel cell system is provided, including an HFR measurement device in electrical communication with a fuel cell stack. The HFR measurement is used online to measure an HFR of the fuel cell stack suitable for calculation of a d(HFR)/d(RH) ratio. A humidity regulator is provided in fluid communication with the fuel cell stack. A controller periodically changes stack operating conditions to perturb an RH of the fuel cell stack, process the HFR response, and compute the d(HFR)/d(RH) ratio. A method for online identification and control of the fuel cell stack humidification is also provided. The d(HFR)/d(RH) ratio is an auxiliary measurement of membrane hydration which is used as a feedback for hydration control.
