Researchers at Aalto University in Finland have developed a new and significantly cheaper method of manufacturing fuel cells. A noble metal nanoparticle catalyst for fuel cells is prepared using atomic layer deposition (ALD). This ALD method for manufacturing fuel cells requires 60 per cent less of the costly catalyst than current methods.
Fuel cells could replace polluting combustion engines that are presently in use. However, in a fuel cell, chemical processes must be sped up by using a catalyst. The high price of catalysts is one of the biggest hurdles to the wide adoption of fuel cells at the moment.
The most commonly used fuel cells cover anode with expensive noble metal powder which reacts well with the fuel. By using the Aalto University researchers’ ALD method, this cover can be much thinner and more even than before which lowers costs and increases quality. [via]
