Default Hymer's new WATT fuel cell system

See a demonstration video of Hymer's new fuel cell system here:
https://youtu.be/naQk7RrWUdI

I'm curious what board members think of this. I'm not an expert by any means, but the idea of another complex system that takes up space and weight, requires propane, and at best only "assists" Ecotrek, does not seem very appealing.

I didn't look at the video but did find this: https://www.wattfuelcell.com/portabl...watt-imperium/ - is that it?

Maybe Hymer is a customer.

I like the specs and that the fuel is propane. The price of it will make it or break it.

Lots of B vans seem to have small propane tanks though so might have to fill up fairly frequently. It would be nice for my Class A with its huge propane tank.


edit: It may have been around for awhile (maybe in development). I saw posts on a forum dating back to 2016.

Fuel Cell
Propane Tank
Solar Cells
Batteries

(no generator or 2nd alternator)

Still sounds expensive but will be very quiet

Been watching these guys for awhile now. If it is real, I think it is a game changer, at any reasonable price. The problem has been poisoning of the cell when used with impure fuel sources, such as commercial propane. If these units have reasonable lifetimes, then I am excited.

Yes, WATT is the company. Here is a press release about the project with Hymer (from March):

https://www.prnewswire.com/news-rele...300609304.html

Hymer has introduced fuel cell technology before, in the European market.

Yes, but as far as I know, it was only the EFOY system that required special proprietary, expensive, hard-to-find fuel canisters.

The thing about WATT is that they claim commercial-quality propane, which would be huge.

I saw a YouTube video this morning with someone from Roadtrek being interviewed, who said that there will be units on sale with the WATT system at the Pomona RV show in October. Seems to me that if the price is reasonable, the WATT system coupled with solar, will make the ideal boondocking vehicle.

I saw a post on Airforums from 2016 - someone said they inquired about the price and was $10K to $15K. Hopefully that's not what it is.

$2K would be high if comparing to a small Honda or Yamaha generator with much higher output but still attractive enough.
