Anode Straight Pore-Porous Transport Layer - Hefei Momenta Energy

Our company’s proprietary highly ordered SP-PTL has over 100 million regular distributed straight-through channels per square meter.
It performs excellently in dot flow fields and 3D titanium mesh flow fields.
It is now ready for low-cost mass production with the size of 25 cm* 25 cm.
The larger size (80 cm * 80 cm) are also under preparation to meet the demand of the larger PEMWE.
The preparation technology of SP-PTL can also be extended to other metal materials, such as nickel and nickel-iron alloys, which are expected to replace the foam nickel and perform well in AEMWE.

Key features

Over 170 million through-holes per square meter with consistent distribution.
Available in sizes up to 25 cm × 25 cm, with larger formats (80 cm × 80 cm) in development.
Adaptable for nickel and nickel-iron alloys for broader electrochemical applications.
High mechanical strength and excellent stability in demanding conditions.
Excels in gas-liquid exchange, electrical conductivity, and membrane electrode support.
High Tensile Strength
Low Contact Resistance
Excellent Flatness
Efficient Mass Transfer

Hefei Momenta Energy specializes in the research and production of key materials and devices needed for the hydrogen industry. Interested? Please contact the Vendor to know more about the product by filling in the contact form.

Hefei Momenta Energy Co., Ltd Hefei Momenta Energy Co., Ltd, founded in 2021 and headquartered in Changfeng County, Hefei, Anhui Province, China, is a high-tech enterprise focused on the research and production of core materials and devices for solid electrolyte membrane electrolysis cells (PEM/AEM/CO2RR), drawing on research and development achievements from the State Key Laboratory of Inorganic Synthesis and Preparation Chemistry at Jilin University over the past decade. The company has established the most complete product series of iridium-based (Ir) catalysts for PEM electrolytic water anodes in China, and holds independent intellectual property rights for its through-hole structure porous transport layer (Ti/Ni SP-PTL) technology (featuring over 170 million regularly distributed straight pores per square meter) and porous transport electrode (Ti/Ni PTE) process, expected to significantly improve electrolysis efficiency and reduce green hydrogen costs. Momenta Energy's proprietary 'Six-in-One' integrated bipolar plate process for PEM electrolyzers, along with its AEM electrolyzer CellularPTE honeycomb electrode and integrated electrode technology, achieved a low-iridium catalyst demonstrating stable operation over 5,000 hours, and the company completed an angel funding round of over ten million yuan to accelerate domestication of PEM electrolyzer core materials and devices. Committed to the concept of 'sincerity, passion, and innovation,' Hefei Momenta Energy works with colleagues across the domestic and international hydrogen energy industry, having established a strategic partnership with Hydrogen Guide Intelligence to jointly build a new ecosystem for domestic electrolyzer development.
