Book excerpt: Proton Exchange Membrane Fuel Cells (PEMFCs) are widely regarded as the next generation of portable power production devices, with uses ranging from powering automotive vehicles to laptops and smartphones. PEMFCs convert oxygen and hydrogen into water and usable electricity and have no moving parts, meaning that they can reach overall efficiencies of 60%. However current Polymer Electrolyte Membranes only work efficiently below 80 °C and at high humidity. At this low temperature, CO poisoning of the Pt electrocatalysts means that only high-grade fuel (low CO concentration
