To compel is to force or drive someone to take action by making that person fear the consequences of not doing so.

To impel is to persuade someone to take action on moral or ethical grounds.

When you are compelled you are coerced, regardless of your wishes. When you are impelled you are made to realize that although the choice may be difficult, it is the right thing to do.
