Polymer electrolyte membrane fuel cells can be used as energy converters in all kinds of systems, from portable electronics and automotive applications to stationary power plants. Membrane electrode assembly (MEA) is composed of polymer electrolyte membrane (PEM), catalyst layers (CL) and gas diffusion layers (GDL) attached on the outer surface of the catalyst layers as shown in the schematic drawing. pub T1 MJIIT none mecoprop, anaerobic membrane bioreactor, kinetic model The impact of mecoprop herbicide 2-(2-methyl-4-chlrophenoxy)-propionic acid [(RS)-MCPP] under different COD:SO42− ratios of 8, 2 and 1, utilizing sulphate as the terminal electron acceptor was examined in an anaerobic membrane bioreactor. Fuel cells An electrochemical conversion device Chemical reactions cause electrons (current) to flow Requires a fuel, an oxidant and an electrolyte ( a substance that contains free ions and acts as a conductor) Typical type of fuel cell is called a proton exchange membrane fuel cell (PEMFC). Efficiency is about 40 to 50 percent, and operating temperature is about 80 degrees C ( about 175 degrees F). Since proton transport through the membrane is dependent on the humidity of the membrane, water management in PEMFC is a key issue. Fuel Cells Presented By: -Taylor Morton -Chris Irvine Overview • Not self contained • Reactants enter cell • Products leave cell • Use combustion to produce electricity • E- transferred through external QuickTime™ and a circuit TIFF (Uncompressed) decompressor are needed to see this picture.
