摘要： : The invention relates to a fused carbonate type of fuel cell comprising an electrolytic body retaining an electrolyte therein which is arranged between an anode and a cathode. Electricity is electrochemically generated by feeding fuel gas and an oxidant to a fuel chamber arranged on the anode side and an oxidant chamber arranged on the cathode side, respectively. The fuel cell is characterized in that the electrolytic body comprises an electrolyte, an electrolyte-holding member for holding the electrolyte and an inorganic binder. The electrolytic body has the advantage that it can be prepared and used in the cell without warping and cracking. Preferably, the binder is an inorganic polymer.

摘要： PURPOSE:To provide a fuel cell which has an excellent electrode which can generate electricity efficiently by preventing any excessive or deficient wetting by electrolyte by providing both a minute-grain layer with small hole diameters and a coarse-grain layer with large hole diameters in the electrode. CONSTITUTION:When the micro-granular layer 3 of an electrode 2 touches an electrolyte body 1, since electrolyte permeates into the minute-grain layer 3 of the electrode 2 due to capillary action, a three-phase interface is formed around the interface between the minute-grain layer 3 and a coarse-grain layer 4, and electrochemical reaction proceeds. In the electrode 2 consisting of the minute- grain layer 3 and the coarse-grain layer 4, the grain diameters of the minute- grain layer 3 are preferred to be below 5mum, and the grain diameters of the coarse-grain layer 4 are preferred to be 10mum-100mum. In addition, the porosities of the micro-granular layer 3 and the coarse-grain layer 4 are preferred to be 35-55vol% and 50-70vol% respectively.

摘要： PURPOSE:To provide a fuel cell which has an electrode which enables the performance of the fuel cell to be maintained stably for a long period by adding at least one of a ferrite and a ferroalloy to at least one of the two electrodes. CONSTITUTION:After an aqueous solution of CMC (carboxymethylcellulose) is added to the copper ferrite (CuO.Fe2O3), the moisture content of the mixture is regulated, and the mixture is subjected to press molding carried out with a molding pressure of 0.5ton/cm . Thus molded mixture, after being dried, is heated in an atmosphere of air. Then, it is maintained at the temperature for 2hr, and gradually cooled so as to obtain an electrode plate. As a ferrite, the complex oxide (M O.Fe2O3) consisting of ferrix oxide and an oxide of a divalent metal is preferred. As a ferroalloy, an alloy consisting of iron and every kind of an element can be used. An electrode is made by using a powder of such an alloy.

摘要： PURPOSE:To obtain a fuel cell which is safe while having high cell performance, when compared with a cell having titanic acid potassium, by employing titanic acid potassium as an electrolyte holding member. CONSTITUTION:In an electrolytic material containing titanic acid lithium as an electrolyte holding material, titanic acid lithium can be produced through the reaction between titania and lithium salt. Lithium carbonate, lithium hydroxide or one of said hydrate, lithium nitrate, etc. can be employed as the lithium salt. Ortho titanic acid, meta-titanic acid, titanium tetrachloride, etc. can be emplayed as other starting material of titanic compound. An organic salt such as titanium alkoxide can be used. Particularly when thermally processing titanic acid potassium fiber (K2O.nTiO2, n=2-8) with a lithium salt, the potassium can be converted into a lithium salt.

摘要： PURPOSE:To secure such an electrolytic plate that is large in mechanical strength and bears strong electrolyte holding power, by using more than two types of electrolytic materials different in a mean grain diameter. CONSTITUTION:alpha-Alumina 102g and lithium hydroxide 92.4g in a mean grain diameter of 0.5mum are mixed with a stirrer. This material powder is processed in thermomechanical treatment for six hours constant at a temperature of 55 deg.C while lithium aluminate is synthesized. With this thermomechanical treatment carried out, alpha-alumina and lithium hydroxide react on each other whereby grain growth takes place up to 5mum or so in maximum from 1mum. This size fraction is pulverized into fines and thereby powder 70wt% of less than the mean grain diamter of 1mum and powder 30wt% having the mean grain diameter ranging from 3-5mum that still remains unpulverized are mixed by a V-type mixer so as not to alter the grain form. Then, after an aqueous solution of carboxymethylcellulose is mixed with 8pts.wt. added, the fines are pressurized and press-molded, kilning them in an electric furnace at a temperature of 1,200 deg.C after being heated and dried up for five hours long at 50-60 deg.C, through which a porous sintered body is obtained. Water absorption of the said porous sintered body is in a range of 50-60%.

摘要： PURPOSE:To obtain an electrolytic body higher in its ability to support an electrolyte and excellent in its mechanical strength by providing an electrolyte supporting layer, on at least one face of the electrolytic body, differing in its pore properties. CONSTITUTION:A multilayer electrolytic body obtained by providing an electrolyte supporting layer comprising nonconducting impalpable powder differing in its pore properties on the at least one face, preferably on the both faces of an electrolytic body constructed by supporting an electrolyte on a long fiber structural body having a self supporting property or a porous sintered body, and supporting an electrolyte on said electrolyte supporting layer. For the particle diameter of the nonconducting impalpable powder used for said electrolytic body, particles fine to the utmost, less than at least 1mum, are preferred in order to raise the electrolyte supporting property thereof. Further, for the electrolyte supporting layer formed by said palpable powder either will do between a paste type electrolyte structure and a matrix type electrolytic body structure. Moreover, it is also proper to form the electrolyte layer in a state where the electrolyte is previously mixed with the nonconducting palpable powder, or to form the same by allowing the former to soak into the latter.

摘要： PURPOSE:To penetrate a catalyst into an electrode base by touching a suspension in which a catalyst, binder, and water repellent agent powders are dispersed to the base evacuating a vacuum container in which the electrode base is placed. CONSTITUTION:An electrode base 1 comprising carbon fiber fabric, porous carbon plate, or metal fiber fabric is placed on a holding plate 3 of a vacuum container 2 provided with the electrode base holding plate 3 having a plurality of passing holes. A suspension of catalyst comprising powder of platinum, palladium, silver, or nickel is sprayed on the electrode base evacuating the vacuum container 2 a vacuum outlet 4 of which is connected to an aspirator. Then a suspension containing a binder and water repellent agent such as fine powder of polytetrafluoroethylene in water is sprayed on the electrode base 1. The electrode base 1 is picked up from the vacuum container 2, and heated in nitrogen gas to obtain an electrode after drying.
