Abstract: An information processing device includes an acquisition unit which acquires use history information indicating a use history of the vehicle for a plurality of items, a derivation unit which derives an output decrease amount for each of the items based on the use history information and output decrease characteristic information, a factor-specific output decrease amount estimation unit which estimates the output decrease amount for each output decrease factor based on the output decrease amount for each item and output decrease factor information, and a control unit. When an output decrease amount for a predetermined output decrease factor is equal to or larger than a threshold value, the control unit executes adhering substance removal control of supplying a nitrogen-enriched gas having a higher nitrogen concentration and a lower oxygen concentration than air to the fuel cell as a cathode gas.

Abstract: In a resin frame equipped MEA, an electrolyte membrane has an outer peripheral overlapping portion that overlaps with an inner peripheral portion of a resin frame member. An ion flow blocking member is provided on the outer peripheral overlapping portion. The ion flow blocking member blocks the flow of iron ions, copper ions, or the like. The ion flow blocking member is formed in an annular shape, and surrounds an electrical power generating region of the MEA. The ion flow blocking member can be provided in the form of a physical barrier or a chemical barrier.

Abstract: A water detection device is provided for a power generation cell. The power generation cell has a reactant gas flow field (oxygen-containing gas flow field) configured to allow a reactant gas to flow along a membrane electrode assembly. The water detection device includes an electrically conductive member and a support member. The support member is an insulating member. The support member covers, and supports an electrically conductive member, and has an opening which exposes part of the electrically conductive member as an electrode. The opening is provided at a position facing a reactant gas flow field.

Abstract: A chromatograph having removable modular analysis units fitting into a chamber within the chromatograph housing, each unit including a column, sample introduction portion and detector. Each modular unit includes a block of thermally conductive material which encloses substantial portions of the sample introduction means and detector and is provided with an exposed surface adapted to contact heating means contained in the chromatograph housing.

Abstract: A detector for use in chromatographs which comprises a capillary passage through which a liquid is to be passed, a first pair of electrodes spaced a distance apart from each other axially of said passage and arranged in an electrically conductive relation to said liquid for causing electric current to flow therethrough, a second pair of electrodes spaced a distance apart from each other axially of said passage between said first pair of electrodes and arranged in electrical contact with said liquid in said passage, and means connected to said second pair of electrodes for measuring changes in the potential difference therebetween.

Abstract: A chromatograph provided with a new and improved purge system for the sample introducing chamber, wherein a first carrier fluid supplying conduit is connected to the chamber adjacent to the sample injection port thereof and a second carrier fluid supplying conduit is connected to the fluid path between the column and the connecting point of the first conduit and the chamber. When a sample is injected into the chamber for analysis, the carrier fluid is supplied into the chamber through the first conduit to carry the sample components into the column, and when the analysis has been completed, the carrier fluid is introduced into the fluid path through the second conduit to flow upstream through the chamber, thereby preventing any of the sample components remaining in the chamber from entering the column to cause "ghost" peaks or baseline fluctuation in the chromatogram.

Abstract: An electrophoretic measurement system for isotachophoresis includes a potential gradient detector, an impedance converter, a voltage to frequency converter, a signal transmission system composed of, for example, electromagnetic wave transmitter means and its receiver spaced therefrom, frequency to voltage converter means, in series connection. This arrangement facilitates insulation of the sensing electrodes of the detector from the ground and prevents a formation of bubbles and deposits on the electrodes, so that the electrophoresis processes are performed under stable condition and high resolution and high sensitivity are obtained. Besides a higher migration current can be used to shorten analysis time.
