>the plane flew with one propeller powered by a regular Pratt & Whitney aviation fuel engine, the other by a motor fed electricity from a liquid hydrogen fuel cell.

I was curious if it is a fuel cell or if they were just burning hydrogen in place of jet fuel.  I am glad to see it is a fuel cell, burning hydrogen would be a very inefficient form of energy consumption.
