Fuel cells, are expensive, though, and their price is due to platinum, which is a rare metal.

So, being efficient means less money spent on them, and more market share for hydrogen. SOFCs (solid oxide fuel cell) are a type of hydrogen fuel cell that use solid (not liquid) electrolyte to do their job, while being much more efficient.
