/ Anode for Slurry circulation type zn/air battery unit cell

摘要

The present invention relates to a fuel electrode for a slurry circulating type zinc / air cell unit cell, which comprises a slurry supply port (10) for supplying a slurry obtained by mixing zinc and an electrolyte, and a slurry supply port A slurry outlet port 20 through which the slurry supplied through the slurry feed port 10 is dropped downward and a zinc pellet 30 is filtered at a lower end thereof and a permeable member 42 And an electrolyte outlet 50 through which the reaction byproducts permeated through the permeable member 42 and the electrolyte are discharged. The permeable member 42 has a thickness that is greater than the thickness of the zinc pellet 40, The porous foamed polymer is thicker than the diameter of the porous foamed polymer. Thus, by fabricating a porous foamed polymer of rigid material having a thickness larger than the diameter of the zinc pellet, the permeable member disposed at the lower end of the zinc electrode pad can basically facilitate the installation of the permeable member to the lower end of the zinc electrode pad, In addition, the porous structure facilitates the passage of the reaction by-products and the electrolyte, and can withstand the weight of the zinc pellets filtered by the rigid material, thereby improving the battery performance.
