Description
Overview
Freudenberg dry operating gas diffusion layers for fuel cell applications include H24C5 and H23C3. This product group is designed for LT-PEM fuel cell development under dry and very dry operating conditions, offering higher thickness and extended dry diffusion length compared with thinner GDL grades. Both materials are suitable for fuel cell stack development, application-oriented material selection, prototyping and performance evaluation where dry operating behavior is a key design consideration.
