“Mystery” Ceramic Could Lead to Cheaper, Stronger Hydrogen Fuel Cells

They don’t know how it works, but it does.

A team of researchers at Georgia Tech University has developed a new high-tech ceramic material that could make solid oxide fuel cells less costly and less finicky, and much more durable and efficient. The material is called Barium-Zirconium-Cerium-Yttrium-Ytterbuim Oxide. [Ed note: Say that three times fast and you get a gold star.] I don’t know if it’s any less of a tongue twister, but it’s known as BZCYYb for short.

Solid oxide fuel cells are of interest because they can generate energy without the need for an expensive catalyst such as platinum, which is typically used in hydrogen fuel cells. While nanotechnology is enabling the development of hydrogen fuel cells that use less platinum, with BZCYYb the prospects look good for ditching the precious metal entirely in favor of more sustainable technology—if solid oxide systems can be developed in a commercially viable form, that is.
