As the world searches for cleaner, longer-lasting fuels, one promising option is the fuel cell. Research today could lead to the breakthrough that will power the cars of tomorrow.
Fuel cells research focuses on the preparation of catalytic tailor-made porous aerogel carbon electrodes. The catalyst in these electrodes is based on non-noble metal complexes instead of the commonly used and expensive platinum. Use of similar electrode systems in conjunction with transparent organic hydrogels (used as quasi-solid electrolytes) is being explored in photoelectrochemical cells in which hydrogen is produced. The incorporation of compounds, which have an important role in electron transfer processes in natural photosynthesis, in the porous electrode/hydrogel systems are investigated.
