Abstract One of the major challenges of 'low temperature' electrolysis (PEMWE) concerns the availability of the catalyst used to promote the oxidation reaction of water, iridium.
To increase the mass current densities, the strategy proposed in this work is to 'nano-architect' the anode materials by depositing the catalyst in nanometric form on the surface of a porous support, electronic conductor and resistant to corrosion, drawing inspiration from what has been developed in the context of fuel cells.
Our recent work has highlighted the value of using doped tin dioxide aerogels as a catalyst support for low temperature fuel cells (PEMFC). The proposed work consists in developing these materials for electrolysis and then to develop a process to deposit iridium oxide nanoparticles on the surface of the aerogel.
