What's going on inside? Fuel cells are complex devices that rely on many coupled physical and chemical processes to operate. Understanding how a fuel cell works and appreciating how these processes interact is key to realising advanced designs and discovery of new materials. Novel diagnostic techniques are being used to examine the internal workings of fuel cells over a wide range of distance scales (see picture).
