A method of manufacturing an energy storage device electrode in which breakage of electrode particles and warping of a collector are reduced, and internal resistance is lowered by lowering the contact resistance between the collector and an electrode layer. The method manufactures an electric double-layer capacitor electrode, and includes: forming a plurality of grooves that run in one direction in each of a front surface and rear surface of a collector foil; subsequently providing an electrode layer that includes plural electrode particles on each of the front surface and rear surface of the collector foil; and subsequently pressing the electrode layer toward the collector foil to move the plurality of electrode particles along the plurality of grooves until the plural electrode particles dig into the plurality of grooves.

A porous electrolytic solution reservoir which is capable of being impregnated with an electrolytic solution is provided in an exterior case so as to make contact with a separator. The average diameter of the pores in the electrolytic solution reservoir is greater than the average diameter of pores in the separator. The electrolytic solution reservoir is impregnated with a predetermined amount of electrolytic solution, so that the occupation ratio of electrolytic solution within the pores in the separator becomes 50% or more when fully charged, and the occupation ratio of electrolytic solution within the pores in the electrolytic solution reservoir becomes 100% or less when fully discharged.

摘要:
A fuel cell having a receiver extending from a side surface of a stacked-cell body of a fuel cell and adapted to receive surplus electrolyte falling along the side surface, and a barrier disposed on the receiver and adapted to catch the electrolyte discharged from a reserve plate while partially restricting an opening which serves as the outlet of a reaction gas flow path. The electrolyte discharged from one single cell can positively be recovered and returned to the same single cell without causing any substantial pressure loss.

The invention relates to an improvement of the gas sealing at the periphery of the electrode base and separator which constitute the fuel cell. Provided herein is a method for sealing the gas of a phosphoric acid-type fuel cell which comprises filling the pores in the porous material periphery of the cell constituents with fine particles of at least one of silicon carbide and silicon nitride which have undergone surface oxidation treatment, and causing particles to expand in volume through the reaction of the surface oxide of the particles with hot phosphoric acid that yields phosphate compounds, thereby clogging the pores.
