Direct alcohol fuel cells offer promising features as energy storage vectors in combination with solar, wind and water power. The current drawback of such devices is the use of precious metals in combination with high metal loadings, which results in high costs and a significant amount of metal is wasted despite a high specific surface area of such nanoparticles. So-called organometallic fuel cells (OMFC), in which well-designed molecular complexes are dispersed as electrocatalysts on a conductive support material, can overcome those disadvantages. In contrast to nanosized catalysts, every single metal atom of the molecular complex is involved in the electrochemical reaction, which considerably reduces the required metal loading. The rational design and optimisation of molecular catalysts offer a better selectivity and reactivity control, thus allowing to avoid the formation of poisoning species. Hydrogen production out of alcohols is interconnected with the reversible formation of protons and electric current. Accordingly, hydrogenase enzymes are the most efficient biological systems for the mutual interconversion of hydrogen into protons and electrons. NATPOWER seizes the opportunity to implement binuclear complexes, that have chemical properties similar to the active sites of hydrogenase enzymes, onto appropriate support materials to ensure their electrocatalytic activity.
