Hydrogen vs. Battery Electric Cars

if more people were using hydrogen, then the cost for it would go down. electric cars will put a drain on the grid if we all used them . so what about a hybrid hydrogen/electric car? gas cars didn't always have the range they have now, so if hydrogen became more widely used, they would improve in range, and the cost of filling them along with the technology to make them better would also improve.  just as electric cars would ( but what do you do with all the dead batteries? ) . for now a combination of electric/hydrogen powered car would give you increased range ( might help when finding a filling station and charging station). but I think hydrogen would be the way to go, just need more  filling stations .
