The new Honda fuel cell car is out and I am confused. There are now gas cars, electric cars, hybrids, and now hydrogen-to-electricity(fuel cell) cars. I always thought that fuel cell tech was basically filters that produced combustible H from H2O, and after combustion rejoined the combustion products with the oxygen molecules to form water as the waste product. I thought that the only major difference in the concept of an H engine and a gas engine was the fuel used, along with a smaller and specificly reformed engine for H due to the per volume power difference between gas and H. The Honda vehicle makes what is an electric car fueled by hydrogen that is bought at a pump, just like we now do with gas. That seems to be a step back or at most a bridge to actual vehicle self-contained, fuel cell production of H. And, isn't stopping to fill up what we are trying to make obsolete? How does H to electricity as propellant constitute an improved answer over burning vehicle self-produced hydrogen in a form of combustion engine? Is not the waste product the same water and no CO2? And, aren't we still trying to bring mainstream what was discovered way back in 1837....making propellant power out of water? Informed answers would be appreciated.
