Can we substitute batteries for fuel cells? They seem near-useless for cars, but very promising for aircraft.

- Pulcinella 9y agoThey are not "useless" for cars, just currently impractical. The problems are the catalyst requires rare, precious metals and, even using hydrogen, efficient fuel storage.
- tarikjn 9y agoCorrect me if I am wrong, but AFIAK the efficient fuel storage issue has been solved with using Methanol/Ethanol (liquid at room temperature) instead of Hydrogen as a fuel.
