I do know a few in the scientific community have been looking for a
better way since the 1980s

New iron catalyst could - finally! - make hydrogen fuel cells
affordable

 For decades, scientists have been searching for a catalyst that
dramatically reduces the cost of fabricating  hydrogen fuel cells. 
....
....
In a study published Thursday (July 7) in Nature Energy, scientists
describe how iron can be combined with nitrogen and carbon to produce
a catalyst that is efficient, durable and inexpensive - the three main
objectives the U.S. Department of Energy (DOE) has identified for fuel
cell research.
