Which car company are developing a hydrofuel car?

Answer 1

Ford.
Although Ford is posting losses due to the restructuring of the company, they are not cutting back in the "Research & Development" department.!
They have several Hydrogen Fuel cell models out on the road, in R&D, but not yet available for retail sale.
Here's one:
