A system produces inert gas and generates electrical power with an electrochemical cell with an anode and a cathode separated by a proton transfer medium separator. The anode includes an oxygen evolution reaction catalyst and a hydrogen oxidation reaction catalyst, and the system is operated in alternate modes: a first mode in which water is electrolyzed at the anode with an oxygen evolution reaction catalyst to form protons and oxygen, the protons are transported across the separator to the cathode and reacted with oxygen at the cathode, and an inerting gas depleted of oxygen is discharged from the cathode; and a second mode in which protons and electrons are produced from a fuel at the anode with a hydrogen oxidation reaction catalyst, protons are transported across the separator to the cathode, and electrons are transported to the cathode through an electrical circuit to produce electrical power.
