The aggregation state of carbon particles in the catalyst slurry directly affects the microstructure of the catalyst layer, mass transfer efficiency, and platinum utilization. In previous knowledge-sharing modules, we discussed how the I/C ratio affects catalyst dispersion, but does having the same I/C ratio or formulation mean the dispersion of carbon particles in the slurry is exactly the same? The colloidal aggregation model developed by Adam Z. Weber and Clayton J. Radke answers this question. This model combines ionomer (Nafion) adsorption, ionomer self-aggregation, and solvent composition to predict the aggregation dynamics of carbon particles in the slurry.1. In the slurry,

Proton exchange membrane water electrolysis (PEMWE) for hydrogen production has become the mainstream solution for green hydrogen projects thanks to its fast dynamic response, high hydrogen purity, and good compatibility with fluctuating wind and solar power. However, the PEM system relies on precious metal catalysts, especially the iridium-based catalysts at the anode, which are used in high amounts and are very expensive, creating a bottleneck for large-scale cost reduction. The national '15th Five-Year Plan' clearly states that by 2030, the average end-use hydrogen price should drop below 25 yuan/kg. Against this backdrop, reducing the cost of PEM hydrogen production while also developing other low-cost green hydrogen methods has become an inevitable trend.
