Hmm...
"He is taller than me" is clearly valid (the "than" is preposition before an object), as is "He is taller than I am" (the "than" is now a conjunction preposition before an object), but "He is taller than I" seems like an accepted contraction rather than a perfectly formed sentence ("I" doesn't mean the same as "I am")...
