  Heyy dude..look broda.....
  lemme 1st tll ya d reasnz y we use H2 intead of normal air
  Firstly lemme start with an example you have seen bike engines say upto 300cc dey all are air cooled ryt now take a look at a basic car engine say maruti 800 is it air cooled to......???????? no we use a coolent ryt....y d reason is the generated heat. Heat is d most important factor in deciding the coolent material so as far as a generator is concerned u can uslf imagine d amount of heat generated........
  Nw here r d reasons y we use hydrogen
  V.imp is its low density secondly high specific heat then highest thermal conductivity at 0.168 W/(m·K) of all gases; it is 7-10 times better coolant than air(wich i think your question for replacement of hydrogen)
  Another very important feature is that its easy detection by hydrogen sensors.
  A hydrogen-cooled generator can be significantly smaller, and therefore less expensive, than an air-cooled one.
  
  Hope ma answer satisfies your question frnd.....😀

  Jishnu is right i support his answer

  Jishnu is absolutely right. But I want to add one more point. Cooling in an machine is nothing but to reduce Hot Spot Temperature(HST) of the windings. Only HST limits the capacity of a machine. If u use air then the heat carried away by the air is less than that of hydrogen. So hot spot ll be attained for lower loads hence decreasing machine capacity.
