> Its a a series of pumps, filter and tubes, and that is if we don't consider the tank. All of that is IN ADDITION to everything a normal EV also has. As if battery powered cars have no pumps, filters and tubes... And a tank is literally just a tank, with no complexity inside it. It allows you reduce the amount of batteries you need to carry by nearly 2 orders of magnitude. This is a significant reduction in cost and complexity. > Look at this simple design, I'm sure they can't wait until they can finally mass produce it, so easy: https://global.toyota/pages/news/images/2020/12/09/1200/005.jpg https://global.toyota/pages/news/images/2020/12/09/1200/005.... You see a battery in the back, 3 hydrogen tanks, and the fuel cell stack in front. This is in fact quite simple. > And every car maker disagrees with you that it doesn't cost much. Most car makers have never even bothered to look seriously at fuel cell cars. The only companies that did think they can make one for the same cost as a Corolla. That should tell you something. > Maybe in some future it can be built as cheap as you say, but not now. So you would really have to compare it to some future EV as well. > Fuel cell have been studied for 60 years, and their efficiency is still not good. Li-Ion has made far more progress in far less time and is still improving significantly year over year. Nobody has announced anything close to that in terms of improvement for fuel cells. > And even if there were such announcements, there is still a long way to go for fuel cells to catch up to current battery tech. The problem is that you're just stuck in the past. Fuel cells have advanced to the point where they are a disruptive threat to battery electric cars. The notion that batteries have some massive lead is a claim completely at odds with reality. You're going to see cheap, long-ranged fuel cell cars in the coming few years. Due to advances in hydrogen related technology, batteries will lose every single advantage they enjoy, including the ability to refuel at home and cost per mile of driving. That is a big problem that battery powered cars will face.
