A comma is used when the phases of the two elements in contact are the same. For example, you would use a comma for something like Fe3+(aq),Fe2+(aq). A | is used when the phases of the two elements in contact are in different phases. For example: Cu(s)|Cu2+(aq). A | can also indicate that a pourous disk/wall is being used between the anode and cathode instead of a salt bridge.
