As an additional note:
Quote: "Note that a subject form without a verb (eg. as well as he) is unusual in this structure in modern English.", unquote. Micheal Swan,
Practical English Usage, p. 70.
I would just say:
"He is more intelligent than her."
The verb may be left out with the structure with "than":
"He has more time than we (have)."
A very important note:
Quote, "When than/as is followed by he/she/it + verb, we normally keep the verb", unquote:
"You are stronger than he is." "His is not so strong as you are."
