Siqens is developing a new type of fuel cell system that combines the advantages of the powerful hydrogen fuel cell with the advantages of the direct methanol fuel cell (available and easily storable fuel). The use of the Siqens fuel cell in a hybrid system as a range extender reduces the weight and cost of the energy supply and solves the range problem of a pure battery solution. They are characterized above all by their efficiency, modularity and the high degree of purity of the hydrogen produced.
