A direct impure water electrolysis (DIWE) approach generates green hydrogen in a modified proton-exchange membrane pure water electrolyzer (PEM-PWE), that avoids fouling, corrosion, deactivation, and side reactions normally caused by the ions in impure or saline waters. Conventional electrolyzers require ultrapure deionized (DI) water as feed because: 1) the proton-exchange membrane (PEM) and electrocatalysts are readily poisoned by the anions, e.g., chloride, and cations, e.g., sodium, calcium, and magnesium that are present in seawater or brackish water; and 2) the chloride anions readily form chlorine at the PEM-electrolyzer anode, which is toxic and corrosive. This adds substantially to the cost and complexity of the electrolyzer plant due to the water treatment plant needed for producing ultrapure DI water. The tolerance of impure water as described herein avoids reverse osmosis and deionization requirements steps which is beneficial for use in semi-arid regions with a paucity of fresh water.

A direct impure water electrolysis (DIWE) approach generates green hydrogen in a modified proton-exchange membrane pure water electrolyzer (PEM-PWE), that avoids fouling, corrosion, deactivation, and side reactions normally caused by the ions in impure or saline waters. Conventional electrolyzers require ultrapure deionized (DI) water as feed because: 1) the proton-exchange membrane (PEM) and electrocatalysts are readily poisoned by the anions, e.g., chloride, and cations, e.g., sodium, calcium, and magnesium that are present in seawater or brackish water; and 2) the chloride anions readily form chlorine at the PEM-electrolyzer anode, which is toxic and corrosive. This adds substantially to the cost and complexity of the electrolyzer plant due to the water treatment plant needed for producing ultrapure DI water. The tolerance of impure water as described herein avoids reverse osmosis and deionization requirements steps which is beneficial for use in semi-arid regions with a paucity of fresh water.

In the present invention, a third catalyst that promotes the bonding of hydrogen and oxygen is disposed on the anode side of an electrolyte membrane (51). Even when hydrogen generated on the cathode side passes through the electrolyte membrane (51) and enters the anode side, the action of the third catalyst enables said hydrogen to bond with oxygen generated on the anode side, thereby converting into water. This makes it possible to reduce the concentration of hydrogen in the gas discharged from the anode side. Particles of the third catalyst have a hollow structure with a cavity therein. Therefore, the amount of the third catalyst used can be reduced while maintaining the surface area of the particles. Additionally, because the particles of the third catalyst have an opening, the movement of water, hydrogen, and oxygen at the anode side is less likely to be inhibited. Accordingly, reductions in the reaction rate of electrolysis on the anode side can be suppressed.

In the present invention, a third catalyst that promotes the bonding of hydrogen and oxygen is disposed on the anode side of an electrolyte membrane (51). Even when hydrogen generated on the cathode side passes through the electrolyte membrane (51) and enters the anode side, the action of the third catalyst enables said hydrogen to bond with oxygen generated on the anode side, thereby converting into water. This makes it possible to reduce the concentration of hydrogen in the gas discharged from the anode side. Particles of the third catalyst have a hollow structure with a cavity therein. Therefore, the amount of the third catalyst used can be reduced while maintaining the surface area of the particles. Additionally, because the particles of the third catalyst have an opening, the movement of water, hydrogen, and oxygen at the anode side is less likely to be inhibited. Accordingly, reductions in the reaction rate of electrolysis on the anode side can be suppressed.
