Interest in electric and hybrid vehicles continues to grow across the globe. The world economy saw EV sales go from around 315,000 in 2014 to 536,000 in 2015, and trends so far for 2016 show that the number of vehicles sold this year is on track to far exceed numbers we’ve seen in previous years.
Moving EVs forward
But in order to make these cars, there needs to be an energy storage source that is not only sustainable, but cheap to produce, with high efficiency, and can be easily mass produced. One of the leading contenders in that race has become fuel cell technology.
In recent years, new materials and better heat management processes have advanced fuel cells. Now, researchers from Lawrence Berkeley National Lab’s NERSC center (including ECS Fellow Radoslav Adzic and ECS member Kotaro Sasaki) are putting their chips on polymer electrolyte fuel cells (PEFCs) to be at the forefront of fuel cell technology due recent finds. In a new study, the group showed that PEFCs could be made to run more efficiently and produced more cost-effectively by reducing the amount of a single key ingredient: platinum.
While fuel cells date back to 1839, they spent a majority of their existence as laboratory curiosities. It wasn’t until the 1950s when fuel cells finally made their way to the main stage, eventually going on to power the Gemini and Apollo space flights in the 1960s.
