Is there an alternative anode (except of stainless steel or galvanized steel) that can be used effectively and without deteriorating the quality of the bath in copper/cyanide plating?

I don't think I would choose either stainless steel or galvanized steel. I would suggest solid copper cast anodes, or copper chunks in steel or titanium baskets, I think. In the event that you are trying to get some insoluble anode area into the tank I would suggest steel (assuming you don't have stringent discharge regulations against the total non-amenable ferrocyanides can can be produced by steel in a cyanide bath).
