Fuel cells have existed (at least in theory) since the early 1800s, but have spent much of their existence as laboratory curiosities. It wasn’t until the mid-1900s that fuel cells finally got their time in the spotlight with the first major application in the Gemini and Apollo space flights.
While fuel cells have moved forward in the competitive field of energy storage, there are still many barriers that researchers are attempting to overcome. Especially today, with society making a conscious effort to move toward more sustainable types of power, much emphasis has been put on solid oxide fuel cells and moving them from the lab to the market.

A team of researchers from Washington State University believes they may have taken a crucial step in doing just that.
Moving fuel cells forward
The team recently published a paper detailing what they believe to be a key step in SOFC improvement and eventually implementation in the marketplace. These small improvements could mean big changes.
SOFCs, unlike other types of fuel cells, do not require the use of expensive materials (i.e. platinum) to develop.
“Solid oxide fuel cells are very fuel flexible in contrast to other kinds of fuel cells, like alkaline fuel cells,” Subhash Singhal, Battelle Fellow Emeritus at Pacific Northwest National Laboratory and esteemed fuel cell expert, told ECS in a previous interview. “Solid oxide fuel cells can use a variety of fuel: natural gas, coal gas, and even liquid fuels like diesel and gasoline.”
