6. Conclusions In this paper we have proposed a novel concept for a proton flow battery – a reversible PEM hydrogen fuel cell with an integrated solid-state MH storage electrode that can be used to store and resupply electrical energy without formation of hydrogen gas.
Essentially a proton battery is a reversible PEM fuel cell with an integrated solid-state electrode for storing hydrogen in atomic form, rather than as molecular gaseous hydrogen in an external cylinder. It is thus a hybrid between a hydrogen-fuel-cell and battery-based system, combining advantages of both system types.
Published in the International Journal of Hydrogen Energy (January, 2014), the research found that, in principle, the energy efficiency of the proton flow battery could be as high as that of a lithium ion battery, while storing more energy per unit mass and volume.
The composite electrode is found to have acceptable proton and electron conductivity. This electrode is integrated into a reversible PEM fuel cell to make a ‘proton flow battery’. The hydrogen storage and release capacities of the proton flow battery are measured. Tentative proof of the feasibility of the proton flow battery concept is obtained.
The energy (hydrogen) storage capacity of the proton flow battery can in principle be expanded simply by adding storage material to the hydrogen-side electrode, while that of the NiMH (or lithium ion) battery is limited by the quantities of ionic species in the electrodes and electrolyte.
