Some digging and there are advance tickets to Ely available for £5, and Ely to Stansted airport is £14 for a regular ticket.
Yes, there are plenty of cases where you can find cheaper tickets by "splitting" the journey. Many can be found with sites like http://www.splityourticket.co.uk/ but not in this particular case, good spot on splitting at Ely.
Ah, that particular case is because there are no advance fares for the train between Ely and Stansted Airport, so most of the train ticket sites don't bother to look for advance fares for any of the legs.
