This very nearly is a fuel cell. You pour the magic juice in and electricity comes out. That's the same as what a fuel cell does.
Personally I'd go for green methane or bicycles. Hydrogen is too hard to handle. It's tiny molecules, it leaks. On the other hand, a lighter-than-air vehicle lifted as well as powered by hydrogen would be ace. I'm a bit not good with height though. A lot actually.
Delivering a supply of electrolyte presents similar problems to running a chip shop, plus if you're extracting used electrolyte from the car, how do you know it's good value stuff and not watered down? As with a battery physically removed from a car by robotic equivalent of block and tackle, the unit might have to be a kind of security vault with its own computer and tampering alarm.
Power storage on site can be done, however, with a big heavy scary capacitor, or a bank of them. Or put the car chae!rge station next to the local electricity substation.
I also still want to see robot cars capable of at least getting themselves charged or filled or whatever without our participation. And also parking themselves at the supermarket. Just going away when not wanted. In fact a device already exists that meets many of my expectations for a car. It's called a "taxi". Only if you want to visit your sister a hundred miles away then the taxi probably won't want to take you. But it would if it was a robot. Perhaps in the future we will more often hire robot cars for long journeys instead of owning them.
I also want a robot at work that I can operate by remote control from home, so I don't have to go. But if the robot is too good then my employer may decide they don't need me. I can imagine my boss being confused about the system anyway. Although he spends a lot of his day, relatively, commuting in a non-robot car, so it should be just the thing for him too.
