Generating Hydrogen Gas from Wastewater

Abstract

A microbial electrolysis cell for generating hydrogen gas from wastewater has a cavity in an interior region of the microbial electrolysis cell and a cathode at least partially around or within the cavity. An anode at least partially surrounds the cathode. The anode contains a porous, electrically conductive material that can be colonised by microorganisms which generate hydrogen gas from the wastewater. The hydrogen gas that is generated collects in the cavity. A manifold allows one or more microbial electrolysis cell to be removably connected to the manifold. The manifold collects hydrogen gas from the connected microbial electrolysis cells and provides electrical connections to the microbial electrolysis cells. A system for generating hydrogen from wastewater has a wastewater treatment vessel holding a body of wastewater. A manifold has one or more microbial electrolysis cells attached to the manifold, where the anode of each connected microbial electrolysis cell is at least partially immersed in the body of wastewater.
