Well Zero does have access to the grand ability of asking a certain millionaire vigilante for certain things if he can muster up the courage to ask for gadgets. Plus he could find out about the whole amorphous ice thing in school.

I doubt any of the characters know Batman is a millionaire. That would imply that he's revealed his identity to the Titans and I'm certain he wouldn't do that. I'm not even sure if he's entrusted his identity to the other Leaguers yet either (usually Batman is the League member who least trusts the others... Superman being the only exception).
