Microbial Electrolytic Cell

摘要

System and methods for efficiently capturing hydrogen gas from a microbial electrolytic cell. Certain aspects of the invention describe microbial electrolytic cells in which the cathode is located above the anode and proximal to a fluid level and a gas headspace in the single-chamber microbial electrolytic cell. In other aspects, the invention relates to improved and high volumetric production rate of hydrogen gas effected by increasing the geometric surface area of the electrodes. Combinations of these aspects also are contemplated.
