I checked out the Toyota Mirai - it does indeed use hydrogen gas cylinders from what I can tell. So this research is targeting simply the ability to transport hydrogen.
Ironically, the ships that carry all that ammonia to Asia almost certainly used fossil fuels and who knows what the carbon footprint around building the membranes for the hydrogen transfer is like
