PURPOSE:To secure such a fuel cell that is able to bring its stable capacity into full play for hours, by weakening the water-repellent properties of an anode ribbed electrode base plate, while increasing an occluding quantity of an electrolyte. CONSTITUTION:As a ribbed electrode base plate serving as the anode, a porous carbon sintered base plate subjected to carburization at a temperature of 900- 1,600 deg.C, desirable 1,000-1,300 deg.C is used, while as a ribbed electrode base plate serving as the cathode, a base plate subjected to graphitization at a temperature of more than 1,700 deg.C as in the past is used, respectively. With this constitution, an electrolyte holding quantity at the initial stage increses and, what is more, an absorbing or feeding function is improved in a manner conformable to variations in electrolytic mass of an electrolytic layer, therefore a sufficient electrolyte holding quantity to electrolyte reduction to be brought out during operation of a fuel cell is secured in consequence, thus cell capacity is stably securable for hours. |
