Previously, the Manchester researchers led by Professor Andre Geim and Dr. Marcelo Lozada-Hidalgo found that one-atom thick materials like graphene are highly permeable to protons, nuclei of hydrogen atoms. However, they also found that other 2-D materials such as molybdenum sulphide (MoS2), that we
Dr. Marcelo Lozada-Hidalgo said: "There is a lack of proton-conducting materials that can reliably operate between 100C and 500C. However, this is the sweet spot temperature range for optimum operation of fuel cells and other hydrogen technologies. Atomically-thin micas work rather well in this te
