Galvanic protection of multiple materials maintaining electric connection

I am looking for the best way to prevent corrosion between two different materials while maintaining electrical contact between them. Specifically, I am wondering about carbon fiber panels placed on an aluminum base and exposed to seawater. Carbon (graphite at least) has a much higher galvanic potential than aluminum so I'm assuming the aluminum will corrode. I cannot place an insulator between them as they need to be electrically connected. Would it suffice to use a typical sacrificial anode? Or might I place another material, like stainless steel, between the carbon and aluminum and reduce the effect?
