If you breed a normal leopard gecko to a Bell albino leopard gecko, you will get all normal appearing babies. These normal babies will be heterozygous (het) for Bell albino, meaning they will carry one hidden copy of the Bell albino gene. A gecko needs two copies of the gene to actually look albino. Albino and normal do not mix to make an "in-between" look in the babies.
This website has a great little tool that lets you plug in gecko parents and see what the babies will be: Leopard Gecko Genetics Calculator
Also, this web page is some good basic reading for understanding genes and the way they work in leopard gecko breeding: The Learning Center - Genetics 101
But... depending on the Bell albino, you might end up with different color/pattern than a "regular" normal. If the Bell has any stripe, jungle, or hypo in its genetic background, then you might end up with variations on normal. The resulting hatchlings might have stripe, jungle, or aberrant patterns, and all of them will be het Bell.
