Fuel cells and batteries

Fuel cells and batteries

Materials for fuel cells and batteries are powders, concentrated dispersions, membranes and also catalysts. The range of tasks and developmental directions cannot be comprehensively described here, but a brief outline shows the multiplicity and the necessity to apply several analytical methods in a complex way. The development of new materials for hydrogen storage and lithium ion batteries should result in high energy and power densities, e.g. in automobiles to release the power in a fast and efficient way. Research is currently searching for new anode materials, because graphite electrodes still limit the range of electric vehicles. A further point is research on nanostructured electrodes for fuel cells and superconductors.
