Introduction

With the rapid advancement of fuel cell technology, performance requirements for gas diffusion layer (GDL) materials such as carbon paper and carbon cloth  have become increasingly stringent. Yuanhang Industrial Furnace, in deep collaboration with renowned domestic research institutions and universities, has developed this high-temperature experimental furnace integrating both carbonization and graphitization functions. By precisely controlling low-temperature, medium-temperature, high-temperature carbonization, and ultra-high temperature graphitization stages, it significantly enhances the electrical conductivity, thermal conductivity, and thermal stability of carbon paper.

Technical Advantages of Yuanhang Integrated Experimental Furnace

• ? Extreme High-Temperature Capability: Full-range processing capability from room temperature to 3200°C, meeting the most advanced material research requirements.
  ? Square Furnace Chamber Design: More space-efficient than circular chambers, greatly facilitating stacked placement of carbon paper and arrangement of carbon cloth stretching fixtures.
  ? Dual Precision Temperature Measurement: Equipped with both thermocouple and two-color infrared pyrometry, ensuring greater accuracy in low-temperature ranges and enhanced stability in high-temperature ranges.
  ? Silent IGBT Power Supply: Compared to traditional power supplies, it offers quieter operation, higher efficiency, and lower harmonic interference, making it ideal for installation in research buildings.
  ? Modular Integration: Highly integrated power supply, water cooling, furnace body, and protection systems, with a compact footprint supporting installation on upper floors.
  ? One-Touch Automatic Door: Optimized design for researchers, eliminating manual operation of the furnace door and insulation cover through fully automated equipment functionality.

Process
