Solid oxide fuel cells that can use conventional fossil fuels as well as hydrogen are set to take a larger role in the energy game
This figure shows the crystal structure of Sc - doped BaZrO3 to be used as an electrolyte material in intermediate temperature solid oxide fuel cells (IT - SOFCs).
Typically, silicon has been used after lithography and etching as a supporting component of small oxide fuel cells.
Strontium cobaltites are just one example of a class of materials known as transition metal oxides, which is considered promising for a variety of applications including electrodes in fuel cells, membranes that allow oxygen to pass through for gas separation, and electronic devices such as memristors — a form of nonvolatile, ultrafast, and energy - efficient memory device.
That's been a high hurdle for devices called solid oxide fuel cells (SOFCs) that convert fuels — such as methane and hydrogen — directly to electricity without burning them.
