Researchers are developing a new combinatorial toolkit to evaluate hundreds of potential PEM fuel cell materials in a single experiment. The goal is to double membrane durability and cut costs in half. This project involves creating low-cost, thermally stable membranes using a 'formulation approach' that combines different polymers.
Researchers have developed a new proton exchange membrane (PEM) material that retains conductivity even at low humidity, overcoming a significant challenge for fuel cells. This breakthrough, achieved through self-assembling block copolymer materials, has the potential to increase the efficiency and feasibility of hydrogen-based energy ...
Scientists have made a breakthrough in molecular electronics by controlling the conductivity of molecules on a single atom. This innovation allows for the creation of ultra-small and efficient devices, requiring less energy to power and producing less heat than conventional transistors.
