Anion Exchange Membrane Water Electrolysis(AEMEL)
■ Technology
▶ Low-carbon hydrogen is one of the solutions for achieving net-zero carbon by 2050, with water electrolysis playing a crucial role.
▶ MEA module for AEMEL employs Zerogap structure design, featuring low module impedance and high safety. It can be combined
with green power to produce low-carbon hydrogen, driving CO2 circular reuse, grid regulation, and related decarbonization
applications.
▶ OH- ions serve as the ionic conduction medium in AEMEL, facilitating the cathodic water splitting to produce hydrogen and the
anodic generation of water and oxygen through a continuous electrochemical reaction.
■ Feature
▶ High Efficiency—Hydrogen production efficiency is higher( ≥ 80%HHV), with rapid response to power fluctuations(reaching 100%
load within 5 minutes)
▶ Cost-Effective—Utilizing non Nobel metal catalyst materials(Nickel-based catalyst), effectively reducing the overall system cost.
▶ Large-area stacked sealing design has developed to enhance hydrogen production pressure and quantity that meets industrial
application demands.
▶ Low-carbon hydrogen production can accelerate the development of net-zero carbon reduction applications.
■ Achievements
▶ Development of the cost-effective self-made Ni-based catalyst, MEA design and mass production process.
▶ Development of high pressure and high efficiency electrolytic hydrogen production AEM module, with a module pressure endurance
of up to 15 barg.The electrochemical performance is over 1.2 A/cm2 at 1.9V(~10kW)
▶ The H2 production rate is over 2.0 Nm³/h and the power consumption is less than 53.5 kWh/kg-H2 via AEM electrolyser operation.
(Power consumption of AEM stack ≦ 50kWh/kg-H2)
▶ Currently, AEM electrolyser can supply stable hydrogen at 9 barg. In the future,the electrolyser pressure endurance will be enhanced
to 30 barg through the improvement of stack design and system integration.
▶ AEM electrolyser has successfully supplied hydrogen at up to a 10% blend ratio to gas turbine power generator, delivering the stable
electricity output.
