However, PEM uses iridium, one of the rarest of all traded precious metals, as the catalyst in its electrodes.

Key Points: 
  • However, PEM uses iridium, one of the rarest of all traded precious metals, as the catalyst in its electrodes.
  • Toshiba developed an iridium oxide nanosheet laminated catalyst that reduced the iridium requirement to 1/10 in 2017.
  • The company has now developed large-scale production technology that deposits the catalyst over a maximum area of 5m2 at one time.
  • Using Toshiba's laminated nanosheet structure in the catalyst layer successfully reduces the required iridium to 1/10, while maintaining the water electrolysis performance (Fig.
