I need help to improve my neat SALT WATER Voltaic cell. I started with copper as my positive elactrode and aluminum as the negative electrode. The result is 337.5 millivolts. Then, I temporarily used a steel plate and I got 830.0 millivolts. That was better, but its an alloy and not pure iron. So, is there a better metal that can beat both of them? I need to get to 1 volt or better. So what metal will do that in salt water?

Mr. Davis seeks information to construct a voltaic (“galvanic”) cell whose potential would equal or exceed one volt using a salt-water electrolyte. I found a short treatise on that subject at https://cathwell.com/galvanic-series/. A zinc-titanium electrode pair would produce just slightly in excess of one volt in salt water. Other combinations are listed in the referenced article.
