About a dozen years ago, my company was contracted by Delphi (formerly part of General Motors) to work on a prototype solid-oxide fuel cell system they were developing for automotive power and large truck APU systems. The prototype was successful, but because it relied on platinum it was too expensive to produce at a reasonable cost. BMW and Peterbuilt both installed a few of them as test platforms, but the project got shelved because it could not be made profitable. I still believe that hydrogen fuel cells could be a long-term answer as onboard power plants for electric cars (such as Toyota demonstrated with their Mirai) or as stationary power for recharging stations. But before they could ever be part of mainstream production someone needs to figure out how to eliminate the need for platinum in the cell.
