That's a good point. Transmission losses in the US are estimated to be roughly 5%: https://www.eia.gov/tools/faqs/faq.php?id=105&t=3

So to beat that, you have to use less than one fuel cell to transport 19 other fuel cells. I honestly have no idea whether that's easy or not.

I would consider our transmission of electrical energy to be very efficient. To transmit power thousands of miles and only lose a few percent is remarkable.

If I recall correctly, hydrogen storage is lossy as well, because it escapes most containers, slowly.
