When I used the term fuel cell, I was not limiting it to hydrogen as the fuel. Can't one consider a fuel cell as simply a type of non-rechargeable/non-reversible battery in which one of both "electrodes" is easily or continuously replaced? In fact, Wikipedia defines the zinc-air battery as both a battery and a fuel cell.
Now, if the zinc were replaced with something else that is easily oxidized (like methanol), it would still be a battery and a fuel cell.
I believe development of batteries and fuel cells can and should continue on simultaneously. At present, fuel cells seem to have the advantage of producing less toxic by-products and/or using more readily available electron donors.
