摘要:
An adjustable fuel delivery regulation assembly is provided which can be disposed within a direct oxidation fuel cell system, or the fuel reservoir or fuel tank that supplies such a system. One embodiment of the fuel delivery regulation assembly is a shutter assembly, which includes two correspondingly perforated components. The two components can be positioned relative to one another such that the apertures in each component are aligned in certain ways. In an open position, the apertures are substantially fully aligned to permit full fuel flow. In a closed position, the apertures are offset such that there is no opening; thereby fuel flow is restricted. Intermediate positions allow adjustments in the amount of fuel flow proportional to the size of the openings. In accordance with another embodiment of the invention, a set of rotatably mounted slotted rods is inserted into a housing through which fuel can flow through openings in the housing. When the rods are rotated to a first position, the slots in the rods are aligned with the openings in the housing. When the rods are rotated to a closed position, the slots are not lined up with the openings, and fuel flow is thereby restricted. Intermediate positions allow controlled fuel delivery. A louvered assembly is also provided. Automatic and manual control systems for the adjustment of the positioning of the various components in the fuel delivery regulation assemblies are also provided.
摘要:
The tool comprises, in a casing (2), electrically operated components and a housing (4) to accommodate a battery (3) that powers the said components, with detachable means (10, 24) of securing the battery in its housing in a position of mechanical locking and electrical connection to the said components and in a position in which it is mechanically retained in its housing but electrically disconnected. The securing means (24) are designed to retain the battery (3) in the electrically disconnected position only by friction (24, 31), thus avoiding any wrong move.
摘要:
An electronic apparatus according to the invention can be powered by a fuel cell unit and secondary battery unit. Power supply management utility executed by a CPU displays the states of use of the fuel cell unit and secondary battery unit. If a predetermined operation is performed in response to the displayed states, using a pointing device, the power supply management utility permits various types of setting related to the use of the fuel cell unit and secondary battery unit to be performed.
摘要:
A metallic separator for a fuel cell has excellent corrosion resistance and contact resistance, even when a gold coating is applied directly without a surface treatment by a nickel coating. The metallic separator for a fuel cell, comprising stainless steel having a surface, can be obtained by coating at 2.3 to 94 % of area rate on the surface without a surface treatment.
摘要:
A stack of direct methanol fuel cells exhibiting a circular footprint. A cathode and anode manifold, tie-bolt penetrations and tie-bolts are located within the circular footprint. Each fuel cell uses two graphite-based plates. One plate includes a cathode active area that is defined by serpentine channels connecting the inlet and outlet cathode manifold. The other plate includes an anode active area defined by serpentine channels connecting the inlet and outlet of the anode manifold, where the serpentine channels of the anode are orthogonal to the serpentine channels of the cathode. Located between the two plates is the fuel cell active region.
摘要:
A portable fuel cell powered electrical generator. The portable fuel cell generator can be provided in a towable trailer, or it can be a portable enclosure which is movable on a trailer. A hydrogen fuel source is transported with the fuel cell generator. The electricity provided by the fuel cell generator can be supplied in as AC or DC current. Power conditioning occurs within the trailer or enclosure.
摘要:
An electrochemical device includes at least one carrier substrate, and a stack of functional layers including at least one electrically conducting layer that includes metal oxide(s), and a multicomponent electrode including at least one electrochemically active layer, at least one higher-conductivity material and at least one network of one of conducting wires and conducting strips. The higher-conductivity material has a surface resistance that is lower than a surface resistance of the electrically conducting layer. The stack of functional layers is arranged between two substrates, and each may be rigid, of glass type or rigid polymer or semi-rigid or flexible of PET type.

摘要:
An electronic apparatus has a multiplicity of display units including an electronic viewfinder and a liquid crystal display (LCD) panel. The apparatus has various display modes. The remaining battery power, i.e., estimated amounts of remaining battery times relative to a current remaining battery capacity, are calculated for the respective display modes. The calculated remaining battery power is collectively displayed as the remaining battery power information on the respective display units. The remaining battery power can be obtained for all the display modes even when the battery is being charged, so that a user can always grasp the remaining battery power of any of the display modes.
