Titanium Fiber Sintered Electrode For Hydrogen Fuel Cell

Product Introduction

Titanium fiber sintered sheet is a porous metal material produced by sintering micron-grade titanium fibers at high temperature. During the sintering process, titanium fibers are bonded together at their contact points, forming a stable three-dimensional porous structure with interconnected pores.

This material combines high strength, low density, excellent corrosion resistance, and superior permeability, making it suitable for a wide range of demanding applications including industrial filtration, chemical processing, aerospace components, medical devices, and hydrogen fuel cell systems.

The highly porous structure provides a large specific surface area and uniform pore distribution, which significantly improves filtration efficiency and fluid permeability.

Product Advantages

Excellent corrosion resistance in aggressive chemical environments

High strength and structural stability under high pressure conditions

Low density and lightweight structure

High porosity and permeability

Uniform pore size distribution

Good formability, allowing folding and bending during processing

Product Characteristics

Micron-grade titanium fiber filaments are produced using a mechanical manufacturing process, which maintains the chemical composition and mechanical properties of the original titanium material.

After fiber preparation, the manufacturing process typically includes:

Fiber mixing

Combing and orientation

Mechanical pressing

Vacuum sintering

The resulting sheet forms a three-dimensional titanium fiber skeleton with interconnected pores and nodes. Compared with titanium powder sintered sheets, titanium fiber sintered sheets provide:

Higher mechanical strength

Better electrical conductivity

Improved permeability

Technical Parameters

(Custom specifications are available according to customer requirements.)

Hydrogen Fuel Cell Applications

Titanium fiber sintered sheets are widely considered a promising material for hydrogen fuel cell applications due to their excellent mechanical and chemical properties.

In a hydrogen fuel cell:

Hydrogen gas enters the anode, where it is split into protons and electrons

Protons pass through the electrolyte membrane

Electrons flow through an external circuit, generating electricity

At the cathode, protons and electrons react with oxygen to produce water

Titanium fiber sintered sheets can be used as the Gas Diffusion Layer (GDL) in both the anode and cathode.

Advantages in Fuel Cells

Excellent gas diffusion performance due to the porous structure

High mechanical strength under compression

Superior corrosion resistance in electrochemical environments

Longer service life compared to carbon-based GDL materials

Reduced system weight, improving fuel cell efficiency

Typical Applications

Hydrogen fuel cells (Gas Diffusion Layer)

Industrial filtration systems

Chemical processing equipment

Aerospace filtration components

Medical filtration devices

High-pressure filtration systems
