Fuel cell using liquid electrolyte

摘要

An electrolyte-type fuel cell, i.e., a fuel cell using a liquid electrolyte, which comprises at least one unit cell comprising a matrix for retaining a liquid electrolyte and a pair of gas diffusible electrodes each having a gas flow passage and provided at both sides of the matrix and in direct contact with the matrix, and a pair of gas supply-discharge means for supplying and discharging a necessary gas to and from the gas passages of the corresponding gas-diffusible electrodes of the unit cell, at least one of the gas passages of the gas-diffusible electrodes being communicated with the matrix through at least one liquid electrolyte passage, at least one demister being provided in the gas flow passage and on the liquid electrolyte passage exposed in the gas flow passage, and a means for generating electrolyte mists being provided at the supplying side of at least one of the gas supply-discharge means can supply a liquid electrolyte to the matrix with a high trapping efficiency of liquid electrolyte mists.
