fuel cell) and reactant consumption (inside the fuel cell). Due to fuel cell design and water management issues etc. the stoichiometry must always be more than one: = n_ feed n_ consumed >1 [ ] = The reactant feed for H 2 and air into the fuel cell stack are now defined by an anode and cathode stoichiometry : n_ H
