Eco-friendly Energy Material for Electrolysis

A core component material for polymer electrolyte membrane (PEM) electrolysis

Titanium Porous Transport Layer (PTL)
PEMEC Anode Porous Transport Layer

In polymer electrolyte membrane electrolysis cells (PEMEC), the porous transport layer (PTL) is a core component that determines hydrogen production efficiency and system durability.
In addition to its primary function of water transport, the PTL performs a number of functions to achieve electrical conductivity and structural stability.

Product Features

Competitiveness
Domestically sourced titanium and ultra-precision processing technology are the key strengths behind Shinsung C&T's porous transport layer (PTL).
Technical Competitiveness Industrial Competitiveness
Titanium processing technology Uniformity of porosity Positioning in the value chain Market growth
Shinsung C&T’s experience with display materials and processing technology is carried over into the precision processing, sintering, and surface finishing of PTLs. In-house manufacturing and analysis facilities enable the sintering technology to achieve optimal porous structures of high density and low resistance. A core component of the PEM electrolysis cell, suppliers of PTLs are limited because of barriers in production cost and technology. With the electrolytic cell as a core technology for today’s mass production of green hydrogen, the market for PTLs is growing fast.
