Order of compounds in cell diagram?

Does the order in which I write a half-cell's components matter? For example, is H2|H+ || Cl-|Cl2 the same thing as writing H+|H2 || Cl-|Cl2?

I believe it is cathode on the right, anode on the left. Whatever is being oxidized is on the left and whatever is being reduced is on the right.

Oh I mean inside the half-cell. Not the order between Cl and H but between H+ and H2. That is, H2|H+ versus H+|H2.

anode is the left and cathode is the right. Also remember aq us closest to the center of the cell diagram than gas and lastly solid.

Thank you, that's what I needed to know.

For the solid on the far right or far left, do they have to be the same?
