Yes , it is common practice to cool large generators with hydrogen . it is an excellent coolant , you have to be careful to use nitrogen as a purging gas. So we start with 100% air and purge to nitrogen and then to hydrogen, and visa-versa going the other way so we don't get an explosive hydrogen ai...
