摘要:
The invention relates to an ionization detector comprising a discharge section which generates ultraviolet rays and a detector section which collects ionic current caused or altered by the photoionization of a sample gas with the ultraviolet radiation. A container holds the two sections together and a pointed cathode is spaced at least several millimeters from an anode in order that the electric discharge may be executed as field-emission discharge.

A fuel container for a fuel cell, comprises a liquid fuel chamber having a space for the storage of liquid fuel, a valve disposed in an outlet of the liquid fuel chamber to discharge the liquid fuel from the space or stop the discharge, a partition wall member movable through the space toward the valve, and a compressed gas chamber communicating with the space and storing compressed gas, the compressed gas imparting a back pressure to the partition wall member so that the partition wall member moves through the space toward the valve, the liquid fuel chamber and the compressed gas chamber being integral with each other. This fuel container is used as a fuel container for replenishing fuel to a fuel container installed in a fuel cell or can be installed into a fuel cell.
摘要:
A fuel cartridge is applicable to the fuel cell comprising an anode, a cathode, a polymer electrolyte membrane and a fuel wicking structure for feeding liquid fuel to the anode. The fuel cartridge comprises a fuel container and a porous fuel transport wick. The porous fuel transport for transporting the liquid fuel to the fuel cell, is incorporated in the fuel container. The fuel cartridge is configured to feed the liquid fuel stored in the cartridge to the fuel cell through the porous fuel transport wick, with assist of the negative capillary attraction which occurs in the fuel wicking structure depending on fuel consumption at the anode.
摘要:
An aqueous solution fuel is fed to a fuel cell by using a propellant gas composed of a pressure has or pressure-liquefied gas. The aqueous solution fuel and the propellant gas are held in an exchangeable fuel cartridge. An ejector for ejecting the aqueous solution fuel from the fuel cartridge to the fuel cell with the propellant gas is provided at the side of the fuel cartridge or at the side of the fuel cell.

C. with excellent durability.
摘要:
When using a measurement of a crossover current density by the Gotesfeld method or a measurement of a methanol permeation coefficient by gas chromatography or by liquid chromatography, a measure for crossover amount may be given but the interrelation with a crossover loss is not clearly known and thus, it could not be possible to evaluate a degree of the crossover loss. The present invention has for its object the provision of a novel measuring method that is able to measure a methanol crossover loss directly.The measuring method is characterized by measuring a crossover loss of MEA for methanol fuel cell from a difference between a voltage when a cathode catalyst layer is not influenced by methanol crossover and a voltage when the cathode catalyst layer is influenced by the methanol crossover.
