Are superconducting galvanic cells possible?

[Bohr'nReady]

My (chemistry) textbook states that maximum work is never achieved in a galvanic (electrochemical) cell due to frictional heating. I've been wondering, could a cell be made with superconducting wires, cathodes, and anodes in order to achieve maximum work? Would this violate the law of entropy?

Heating occurs in the fluid as well. I don't know if you can use a superfluid medium as galvanic cell.
