  • Laminated layer type fuel cell
    Patent number: 4686159
    Abstract: A laminated layer type fuel cell is formed of rectilinear and zigzag portions of channels formed in at least one selected from a group consisting of the gas separation plates, fuel electrode and oxidizer electrodes, thereby equalizing the electrochemical reaction, improving the cell characteristics, and the uniformity of the temperature distribution of the laminate layer type fuel cell.

  • Method of manufacturing an electrode for a fuel cell
    Patent number: 4603060
    Abstract: A method of manufacturing an electrode for a fuel cell comprises placing a coating roller opposing a feeding roller with a space through which an electrode substrate is passed, placing a doctor roller with respect to the coating roller so as to keep a space which is adjustable, arranging a paste reservoir above the doctor roller and the coating roller so that paste flows to the space between the doctor roller and the coating roller, rotating the feeding roller in a specified direction while the coating roller is rotated in the same direction as the feeding roller to transfer the paste on the electrode substrate.

  • Method for the treatment of waste fluids from orange canneries and process for recovering pectic substance therefrom
    Patent number: 4461890
    Abstract: Disclosed is an invention providing an improved method to treat a factory waste, and more particularly for the treatment of pectic waste fluids from orange canneries i.e. the acid- and alkaline wastes. The present invention also provides a process to recover pectic substance therefrom. The method contains the steps of (1) adjusting the pH either in the acidic waste or a mixture of acidic- and alkaline waste to a level over 7.0, allowing the waste or mixture to stand for a period sufficient to effect a substantial saponification of the pectic constituent, adding acid to the waste or mixture to bring its pH below 3, separating the pectic substance from the resultant, and treating the resultant supernatant or filtrate by a biological procedure using an active microorganism, or, alternatively, (2) adding acid to the alkaline waste to bring its pH below 3, separating the pectic substance from the resultant, and treating the resultant supernatant or filtrate by a biological procedure using an active microorganism.
