What does it mean by standard potential of an electrode is the standard potential of the cell in which electrodes lies on the right and hydrogen electrodes lies on the left?

Re: electrodes

Remember that the most positive reduction potential will be at the cathode, getting reduced, and the more negative one will be at the anode. In this case, hydrogen is SHE and is 0.00 V. because the hydrogen electrode lies on the left, in a cell diagram, for example, that means it is at the anode, and the other thing must be more positive.

Re: electrodes

Is it safe to assume the hydrogen cell will be the anode because when calculating E cell standard, any positive number minus 0 will give a postive voltage?
