High-Performance Bipolar Plates (TIMREX® KS, SFG & C-THERM®) Polymer-based bipolar plates rely on TIMREX® graphites as their main functional additives to distribute hydrogen fuel gas, remove heat, and conduct electrical current between cells,.

1. TIMREX® KS and SFG Series: These exceptionally pure primary synthetic graphites (such as KS75, KS5-75TT, and KS150) deliver high electrical and thermal conductivity, mechanical stability, and high corrosion resistance,,. Their optimized particle size distributions also ensure easy processing and low gas permeability, effectively preventing hydrogen or coolant leakage,.
2. TIMREX® C-THERM™: This specialized high-aspect-ratio graphite acts as a powerful secondary performance additive. When added in small quantities, it significantly boosts both thermal and electrical conductivity at low carbon content levels,.

Fine-Tuning Gas Diffusion and Microporous Layers (GDL/MPL) To manage the delicate balance of gas and water transport within the fuel cell, TIMREX® graphites are utilized to precisely control the layer's permeability and porosity,.

1. TIMREX® BNC30: A strongly anisometric, high-aspect-ratio graphite that delivers the highest thermal conductivity and lowest electrical resistivity values among GDL/MPL carbons,,.
2. TIMREX® KS44: An isometric synthetic graphite that provides excellent structural integrity and conductivity for robust gas diffusion layers.

Pore Formers for Solid Oxide Fuel Cells Beyond PEMFCs and electrolyzers, TIMREX® graphite powders are also highly effective when utilized as pore formers in solid oxide fuel cell components, highlighting their versatility across various fuel cell architectures,.

By combining extreme purity (greater than 99.8% carbon) with highly customizable particle morphologies, TIMREX® graphites enable manufacturers to achieve superior efficiency, durability, and safety in next-generation hydrogen fuel systems.
