摘要： PURPOSE:To uniformly, smoothly replenish an electrolyte to each unit cell with a specific water head retained by connecting the upper and lower ends of an electrolyte passage formed in a cell stack to the upper and lower ends of an electrolyte tank which is supported by the cell stack movably up and down and has free space to form a siphone type supply-exhaust passage. CONSTITUTION:A siphone type electrolyte supply and exhaust passage 21 which is connected to each matrix 2 through each branch groove 12 is formed between a cell stack 10 and an electrolyte tank 27. Electrolyte supply or exhaust operation is conducted before or after the reversing operation of the cell stack 10 by moving up and down an electrolyte tank 17 to change water head. By reversing water head applied to each unit cell 1 before and after the reversing operation in electrolyte replenishing operation, the amount of an electrolyte replenished by two replenishing operations is made constant independent of the stacked position of the unit cell 1. The electrolyte is uniformly, smoothly replenished to each matrix and power generation is increased.

摘要： PURPOSE:To efficiently raise the temperature of a cell with a simple device by installing an air supply means which cools combustion gas to an optimum temperature by normal temperature air sucked from the outside in a supply pipeline of combustion gas for a starting burner. CONSTITUTION:When an air cooled fuel cell 10 is started, a valve 26 is opened, and a blower 9 is operated to suck the air in a starting burner 21, then fuel is supplied to generate combustion gas. The combustion gas is circulated in a supply pipeline 15 with the blower 9 and the temperature of a cell 10 is raised. During this operation, the opening of an air supply valve 27 is adjusted to control the amount of air, and high temperature combustion gas is cooled to a certen temperature which is optimum to raise the temperature of the cell 10. When the temperature of the cell is raised to a specified value, the operation of the burner 21 is stopped and the air supply valve 27 is closed to keep the temperature of the cell constant. The temperature of the cell is efficiently raised with a simple device.

摘要： PURPOSE:To smooth supply of an electrolyte while simplifying a construction of an electrolyte supply path by forming a hydrophilic part in the peripheral region of one electrode while punching out an electrolyte supply path on the hydrophilic part. CONSTITUTION:A hydrophilic part is formed on at each single cell, at least one electrode of the respective electrodes 3 and 4 contacting with a matrix 2, for example, on the periphery of the fuel electrode 3. And, the electrolyte supply paths leading to a reservoir from outside running through a single cell 1 and the gas separating plates 5 in the top and bottom lamination direction are punched out on the four corners of of a cell stack as electrolyte reservoirs on the hydrophile part. When the electrolyte is injected into the electrolyte supply paths, the paths 9 are filled with the electrolyte so as to be able to supply the electrolyte on the hydrophile 8 formed on the periphery of the elec trode 3 and inside the matrix 2. Thereby, a simple construction of the electrolyte supply paths can smothly supply the electrolyte.

摘要： PURPOSE:To control temperature of a fuel cell main body only by a flow rate control means to simplify a system and reduce the number of components by arranging an air blower on fuel cell main body side from the junction of an air supply pipeline and circulation pipeline, and connecting a flow rate control means always having a specified opening onto suction side.

A discharge pipe 62 is branched and one joins to the supply pipeline 61 between the blower 2 and the damper 3 to form a circulation pipeline, and the other forms a discharge pipe 64 connected to the atmosphere. The suction pipeline 65 always gives a specified opnening to the flow rate control means by bypassing the electric damper 3. A temperature detector 41 is installed in a fuel cell main body 1 to detect its temperature. A temperature signal is sent to a temperature controller 4 to control the opening of the damper according to the signal.

摘要： PURPOSE:To obtain a uniform current distribution on the electrode layer surface by decreasing the diffusion resistance value from the inlet toward the outlet of fluid paths at diffusion paths where a reaction fluid is diffused i a porous electrode substrate and reaches an electrode layer. CONSTITUTION:An electrode substrate having grooves feeding fuel gas and an electrode substrate having grooves feeding oxidizer gas are closely stuck to both sides of a unit cell consisting of an electrolyte, a fuel electrode, and an oxidizer electrode, and they are laminated to form a fuel cell stack. In this case, the gas feed grooves 4a of each electrode substrate 4 are formed so that the number of branch feed grooves is increased from the inlet section toward the outlet section and the lengths of diffusion paths from the feed grooves 4a to the electrode 2 through the electrode substrate 4 are shortened. Accordingly, the density decrease of the reaction component in a reaction fluid is compensated, a uniform current distribution is obtained on the electrode layer surface, and the cell life can be extended by decreasing the diffusion resistance value toward the outlet section.

摘要： PURPOSE:To present a manifold structure of simple construction further ensured with sufficient air-tightness, by fitting an elastic cylinder, in which the length of an internal circumference is smaller than the length of an internal circumference of a circle circumscribing a fuel cell, to the fuel cell so as to be contacted with angular parts of the fuel cell through packings. CONSTITUTION:An elastic cylinder 10 is selected such that the length of an internal circumference is smaller than the length of an internal circumference of a circle 11 circumscribing packings 9 in four corners a, b, c, d as shown by a broken line in the drawing. By such selection of a diameter, the cylinder 10 can be easily fitted to a cell group 8 while applying pressing force from four directions and closely contacted to the four corners a, b, c, d of the group 8 through the rubber packings 9. In this cylinder 10, restoring force tending to restore the original circular shape is always acted to hold a dimensional change due to thermal expansion between the group 8 and manifolds 12-14 to within a permissible range, and sufficient air-tightness can be ensured despite its simple construction.
