Actually it was Virginia Tech (and Texas Tech) who built the hydrogen powered Explorers. A 2.0L Zetec engine was taken from a Ford Focus and with a modified fuel rail and engine maps the engine ran off hydrogen for the VT truck. We used a series configuration so the engine just ran a generator to power the two drivetrains.
