Microbial fuel cell structure having a plurality of unit cells consisting of sides of each pilar, and Microbial fuel cell having the sturcture

摘要

PURPOSE: A microbial fuel cell structure is provided to improve the effective area of an electrode contacting contacts with fuel and air and to increase the processing speed of effluent and generated amount of electricity generation amount. CONSTITUTION: A microbial fuel cell structure comprises unit cells arranged at on the sides of each prism. The unit cell includes: a membrane-electrode assembly(20) sequentially equipped with a first electrode, an ion-exchange membrane(24), and a second electrode in order; and a holder(10) which accepts the membrane electrode assembly and exposes to which the first and second electrodes are exposed.
