escott Posted July 6, 2019 The problem with hydrogen fuel cells TODAY is that they require a lot of energy to manufacture. This energy likely comes from a coal burning power plant. But in a FUTURE with fusion power, like @rideforever keeps mentioning, this will no longer be a problem. So, the fuel cell will be the high energy density battery of the future and will be a perfect solution to replace internal combustion engines. Share this post Link to post Share on other sites
