The difference between a "galvanic cell" and "electrolyte cell"

    Hi

    Reading Electrochemistry by Hamann [1998, p.237] he says that If a cell has
    a non offset (no DC) ac signal applied it will operate like "galvanic cell"
    rather than an "electrolyte cell".
    I was under the impression that they were the same thing. However, a good
    old search on Google reveled the following difference:

    - Galvanic cell: DeltaG < 0; spontaneous; -DeltaG =
    maximum
    electric work output

    - Electrolyte cell: DeltaG > 0; non-spontaneous; DeltaG = minimum
    electric work needed

    Does this mean that a Galvanic will produce electrical energy and a
    electrolyte cell with produce chemical?

    Can someone clear this up for me?

    Cheers

    Help!

    Is it or isn't it and could you please explain you answer? (No this is not
    an exam question - just a pursuit for knowledge)

    Cheers
