Product Description
Product Presentation
Water Electrolysis Membrane Electrode is a critical component used in the process of water electrolysis. It typically consists of a thin membrane or electrolyte film and two electrodes. Water electrolysis is a chemical reaction in which water is split into hydrogen gas and oxygen gas, and it is a method for producing hydrogen as an energy source.
During the water electrolysis process, the water electrolysis membrane electrode applies electrical energy to water, causing the separation of oxygen ions and hydrogen ions in the water, leading to oxidation-reduction reactions on two electrodes. One electrode (anode) is where the oxidation reaction takes place, while the other electrode (cathode) is where the reduction reaction occurs. Oxygen gas is produced at the anode, and hydrogen gas is generated at the cathode.

Our company's self-developed catalyst offers the following advantages:
High Consistency: Uniform distribution of nanoparticle size.
High Electrochemical Activity: Both ECSA (Electrochemically Active Surface Area) and MA (Mass Activity) are relatively high.
Excellent Durability: The use of high-temperature annealing technology extends the catalyst's lifespan by approximately 30% compared to commercial alloy catalysts

Hydrogen generation by PEM has four main steps:
1. Water hydrolyzes at anode. (2H2O=4H++4e-+O2)
2. 4H+ pass through the ordered MEA(proton exchange membrane coated with ordered catalyst) to cathode.
3. 3. 4e- electrons transport from anode to cathode through external circuit.
4. Hydrogen generation at cathode. ( 4H++4e-=2H2 )

Electrolyzer Structure
PEM Electrolyze Cell
PEM electrolyze is typically composed of end plate, diffusion layer, catalyst layer and proton exchange membrane.
The role of end plate is to fix components, guide current and help distribution of water and gas.
The diffusion layer plays a role as current collector and promote gas-liquid transport.

The core of the catalyst layer is the Triple Phase Boundary (TPB) consisting of catalyst, electron and proton conduction medium, where the electrochemical reactions take place.
For higher hydrogen production rates, a PEM electrolyze is typically stacked with 5 to 100 cells in series.

Electrolyzer Assembly
The electrolyzer adopts zero - distance structure to improve assembly efficiency and maintain strong sealing and low contact resistance.
The energy consumption of the electrolyzer has been greatly reduced with the overall efficiency increased from 73% to 84%.

PEM（Proton Exchange Membrane） Electrolyzer
High Efficiency: PEM electrolysis cells typically exhibit higher electrochemical efficiency. Since they only allow protons to pass through while blocking hydroxide ions, they are often more efficient in producing hydrogen gas.
Low Electrolysis Load: Due to their high efficiency, PEM electrolysis cells typically require lower electrolysis loads to produce the same amount of hydrogen, which can reduce the energy cost.
Fast Response: PEM electrolysis cells offer quick startup and response times, making them suitable for applications that require rapid response.
Lower Operating Temperature: PEM electrolysis cells typically operate at lower temperatures, which can reduce energy consumption.
Smaller System Size: Because of their efficiency, PEM electrolysis cells can often be designed with smaller footprints, suitable for applications with limited space.
