I don’t see anything about this fuel cell being more efficient, just that it continues to produce power “3 minutes, 30 seconds” after the fuel is shut off/runs out.

In practical use it would mean that you’d have to shut your FCEV down a few minutes before you arrived at your destination in order to not waste energy.  (Unless this device can store that 00:03:30 without self discharge.)

In their example of a fuel cell airplane, you could get the same flight time by simply burning fuel a bit slower.
