We have developed two electron oxygen reduction catalysts suitable for different reaction microenvironments, one carbon-based（alkaline and neutral environments）, and the other alloy-based （acidic and neutral environments）. These catalysts have been optimized in terms of geometric morphology, mesoporous/microporous structure, elemental composition, and atomic coordination modes, ensuring high yields and low energy consumption at a fundamental level.

The solid-state electrolyte electrolytic cell is indeed an effective solution to the issue of discharging reaction products in traditional reactors. However, microsphere-type solid-state electrolytes can affect the flow distribution of the electrolyte solution, and the shear stress during assembly can cause the ion exchange membrane to rupture, making the filling process laborious and labor-intensive. In response to these challenges, Yipai Technology has developed a plate-shaped solid electrolyte, which is produced using the XX one-step method and includes microporous channels that can evenly distribute the electrolyte solution and facilitate assembly.

We have developed flexible graphite felt electrodes, semi CCM electrodes, and membrane electrodes for ALK, SE, and PEM electrolysis systems, achieving mass production of these three types of electrodes. Among them, the flexible graphite electrode catalyst has the characteristics of high loading and uniform distribution, high electrode active area, high conductivity, and strong chemical stability. Our proprietary membrane electrodes adopt an ordered catalytic layer structure, which reduces the noble metal loading of the anode catalytic layer. We employ multi-scale interface engineering strategy to regulate the gas liquid solid three-phase catalytic interface to enhance charge transfer kinetics and mass transfer efficiency. Additionally, we utilize computational fluid dynamics to construct a gas-liquid displacement transport model in a porous membrane electrode transport layer, optimizing the gas-liquid diffusion path, and achieving efficient discharge of reaction products.

Given the limitations of mass and charge transfer in electrochemical reaction processes under high electron flux, a strategy for enhancing the construction of solid liquid gas three-phase interfaces has been proposed. By utilizing 3D reconstruction and direct multiphase flow simulation techniques, the formation mechanism and control methods of three-phase interfaces were elucidated; By designing non encapsulated catalyst/binder interface engineering, a multi-layer gradient catalytic layer structure was constructed to induce gas-liquid directional transport, greatly improving the quantity and stability of the solid liquid gas three-phase interface. This optimization greatly enhances the mass and charge transfer process of electrochemical reactions, promoting the reaction system to achieve higher power density and longer service life.

Starting from the design of channel bipolar plates and focusing on the characteristics of three-phase interface reactions on the cathode side, PEM electrolysis cells, SE electrolysis cells, and ALK electrolysis cells suitable for synchronous participation of gas and liquid reactions were developed using electro synthesis of hydrogen peroxide as the starting point.
