Answer 1

Fuel cells are a form of battery.  All batteries work my converting the energy produced by a chemical reaction into an electrical potential.  In a fuel cell, the reaction involved is the combustion of hydrogen with oxygen.  This combustion takes place across a specially engineered membrane so that most of the energy is released as electrical potential and not heat.  The product of the reaction is water.
