The Nernst equation: \(E = E^\circ - \dfrac{RT}{nF}\ln Q\) relates the electrode potential \(E\) to the standard electrode potential \(E^\circ\), temperature \(T\), number of electrons \(n\), Faraday constant \(F\), and the reaction quotient \(Q\) (which depends on concentration). So electrode potential depends on both temperature and concentration of the species involved.
