A research team from the Tokyo University of Science and the Japan Science and Technology Agency has managed to use gallium nitride (GaN) crystals to extract hydrogen from water, which might lead to the development of more efficient processes of extracting hydrogen for the use in fuel cells.

A GaN wafer is connected with platinum using a wire, and immersed in water. Light is applied, and current flows through the water which causes electrolysis, hence producing hydrogen. The efficiency of converting light energy to hydrogen energy using this method is a mere 0.5%, however efficiency was improved 1.3 times by introducing the narrower bandgap material such as InGaN. According to Professor Kazuhiro Ohkawa of the Tokyo University of Science applied physics department, this can be raised to more than 20%.

I’m just wondering if this is the magic metal used in LMG’s Hydroxene :roll:
