Disrupting water electrolysis, this tech couples a Value-Added Anodic Reaction (VAAR) with hydrogen evolution, replacing oxygen evolution with high-value FDCA from bio-based HMF. This dramatically lowers the potential, cutting energy consumption to 3.63 kWh/m3_H2 (20%+ energy savings). Using a green chitosan composite AEM and noble-metal-free catalysts, it achieves material autonomy and shatters cost barriers via a dual-benefit business model.

This tech revolutionizes water electrolysis by coupling cathodic hydrogen evolution with an anodic VAAR (HMF-to-FDCA, bypassing the high OER overpotentials. This thermodynamic leap cuts energy consumption to an ultra-low 3.63 kWh/m3, saving 20%+ in electricity. It features three material breakthroughs: a green, non-swelling chitosan composite AEM with superior conductivity, charge-accelerating heterojunction electrodes, and a stable high-entropy alloy catalyst, achieving key material autonomy.

This ampere-scale MEA system shatters green hydrogen cost barriers through a dual-benefit business model. It lowers power bills with 3.63 kWh/m3 low-energy operation, while the anode co-produces high-value FDCA (a bio-plastic raw material) to cross-subsidize hydrogen costs and shorten ROI. Featuring seamless integration with chemical plants and total material autonomy (domestic chitosan AEM and noble-metal-free catalysts), it secures supply chain resilience.
