www.energy.govCompact, reliable, safe, and cost- effective storage of hydrogen is a key challenge to the widespread commercialization of fuel cell electric vehicles (FCEVs) and other hydrogen fuel cell applications. While some light- duty FCEVs with a driving range of over 300 miles are emerging in limited markets, affordable onboard hydrogen

Alkaline Water Electrolysis - EOLSS
www.eolss.netCell voltage corresponding to ΔG is reversible voltage, about 1.2 V, and TSΔ , heat absorption potential, about 0.28 V. In actual electrolysis, cell voltage is higher than reversible potential and the difference is converted into heat. Since the reaction is endothermic, heat thus caused is absorbed by the reaction until total cell
