Chell is the silent protagonist of Portal and the single-player campaign in Portal 2. Very little is known of her past, beyond her possible abandonment at birth and her stubborn will to live.
Throughout the series, Chell is antagonized by the AI and facility overseer GLaDOS during her testing courses. Wielding only the Handheld Portal Device, she eventually utilizes this device as a means of avoiding hazards and bypassing various sections of the Facility in order to escape.
Unfortunately her escape attempts failed (as seen in Portal 2) where she ends up inside a coma for a few years until she is awoken by a Core known as Wheatley. And to make matters worse, she now has brain damage. Fortunately this doesn't stop Chell from trying to escape once again...
