摘要： PURPOSE:To prevent the movement of an electrolyte in an electrolyte holding matrix and suppress the deterioration of the cell performance by changing the electrolyte saturation absorption quantities of an anode and a cathode so as to decrease the electrolyte saturation absorption quantity of the cathode. CONSTITUTION:A cathode 12 made with a porous substrate 14 and a catalyst carrying layer 15 and an anode 13 made with a porous substrate 16 and a catalyst carrying layer 17 are provided across an electrolyte holding matrix 11, and gas separation plates 18, 20 are arranged outside them to form a fuel cell of a phosphoric acid type, etc. In this case, the electrolyte saturation absorption quantity of the anode 13 is made 3.0-20.0 times as large as that of the cathode 12; particularly for a phosphoric acid type, the cathode side is made 3-6mg/cm and the anode side is made 20mg/cm or less. Accordingly, the decrease of the cell voltage caused by the movement of the phosphoric acid in the matrix 11 from the anode 13 to the cathode 12 can be suppressed, and the life of the cell can be extended.

摘要： PURPOSE:To prevent deterioration in battery performance due to contactness between anode and air by providing a moistened film to the anode. CONSTITUTION:A layer consisting of a conductive and porous material which can sufficiently hold electrolyte is provided on the catalyst layer of anode. As the conductive and porous material, unwoven cloth or woven close of carbon, metal wool or porous plate can be used but any kind of material can be used so long as it is conductive, porous and has resistance for chemicals so that it is not corroded by fuel or electrolyte. If such a conductive and porous layer is moistened by electrolyte, the anode is kept wet. In case the anorite is drained while the battery is not used, contact between air and anode can be avoided and thereby degradation of battery performance can be prevented.

摘要： PURPOSE:To obtain a fuel cell generator with stable cell performance by suppressing the cathode potential and preventing the growth of platinum grains on the cathode when the operation of the fuel cell is interrupted or stopped. CONSTITUTION:During the cell operation, methanol is fed from a fuel reservoir 15 to a cell proper 1 through a fuel feed valve 16, air is guided by an air blower 17 to the cell proper 1 through an air inlet valve 18, and steam and unreacted air is discharged outside the cell through an air outlet valve 19. When the cell is stopped, the connection of the cell proper 1 and a load circuit 2 is opened by a load switch 20, and in conjunction with it, the air inlet valve 18 and air outlet valve 19 are closed. As a result, the feed of oxygen to an air pole is cut off when the cell operation is stopped, and the potential increase at the air pole can be suppressed. The potential essentially suppressing the reaction at a positive electrode is preferably made 0.9V vs NHE or less.

摘要： PURPOSE: To aim at improvement in the operatability of liquid fuel as well as the promotion of miniaturization and lightness of a cell, by making the liquid fuel turn into a state of non-liquidity through a physical or chemical means.
CONSTITUTION: In this invention, methanol, formic acid, formalin or hydrazine, etc., are used by way of example, as the liquid fuel to be used, so that these fuel elements may be turned to a state of non-liquidity, there is a method that uses an adsorbent. As the adsorbent, for example, dextrin, dextran, cilica gel, an active carbon, etc., can be used. In addition, there are some chemical methods such that formic acid is converted into sodium formate, hydrazine into hydrazinium sulfate, and methanol into sodium methylate respectively, and furthermore formaldehyde is converted into paraformaldehyde after being polymerized. Doing like this, if a fuel element 1 being turned to a state of non-liquidity is held in a cartridge body 2 and formed into a cartridge type, operation for attaching/detaching the fuel element to/from a fuel cell becomes very simple.

摘要： PURPOSE:To improve the cell performance considerably by bearing water repellent particles and precious metal for performing catalysis on one face of an ion exchange film to integrate the oxidizing agent electrode and the ion exchange film thereby reducing the contact resistance between the ion exchange film and the electrode considerably. CONSTITUTION:Water repellent particles and platinum catalyst are born on one face of an ion exchange film 1 to form an air electrode 4, while dual function catalyst of platinum and ruthenium is born on the other face of the ion exchange film 1 to form a methanol electrode 7, where said air electrode 4 has the water repellent performance to form the three-phase interface thus to improve the performance as the air electrode for a methanol fuel cell considerably. Since no air gap is formed between the ion exchange film 1 and both electrodes 4, 7 the contact resistance is reduced considerably and carbon dioxide produced from the methanol electrode 7 will never be stored resulting in the improvement of the cell performance. Furthermore the independent process for manufacturing the air electrode and the methanol electrode and assembling in the fuel cell is not required, the manufacturing time can be shortened to 1/5. It can be applied on other type cells and similar effect can be achieved.

摘要： PURPOSE:To obtain a secondary battery which is suitable for electric-power preservation by preventing any branch-like deposit, which might develop during charging, by preparing a negative active material from a molten metal. CONSTITUTION:A battery is actuated at 480 deg.C by using zinc as a negative active material 1, mixture consisting of zinc chloride and sodium chloride (weight ratio, 70 to 30) as an electrolyte 2, and chlorine as a positive active material. At this temperature, the negative active material 1 deposits in a molten state during charging, and any branch-like deposit doesn't develop in the electrode as is seen in ordinary temperature operation. Besides, no short circuits develop between the positive and the negative electrodes during the battery operation, and the function of the charge-and-discharge of the battery can be fully exhibited.
