Gas Diffusion Layers (GDL) for Fuel Cells

Gas diffusion layers (GDLs) are vital components in Polymer Electrolyte Membrane Fuel Cells (PEMFC) modulating all relevant transport processes comprising fuel, oxidants, reaction products, electricity and heat. Gas diffusion layers serve as a functional interface between the gas distribution compartments (structural cell parts, macroscopic scale) and the electrochemically active catalyst layers (reaction layers, processes occurring at the nanoscale). GDLs direct fuels and oxidants to the active sites whilst removing heat and reaction products and electrically wiring the reaction layers with the current collectors.

Brief background knowledge

With the continuous development of new energy technologies, fuel cells, as an efficient and environmentally friendly energy conversion device, are increasingly in demand. In fuel cells, Gas Diffusion Layers (GDL) play a crucial role, which is responsible for evenly distributing reactive gases to the electrodes and conducting electric current. As an important part of GDL, the performance of Graphite Parts directly affects the overall efficiency and service life of the fuel cell.

Main Functions and Characteristics of Graphite Parts

The functions of Graphite Parts in GDL are mainly reflected in the following aspects: firstly, excellent electrical conductivity, which ensures the smooth transmission of current; secondly, good chemical stability, which can maintain stability in various chemical reaction environments; thirdly, excellent gas diffusion performance, which contributes to the uniform distribution of reaction gas. In addition, the high porosity, low density and good thermal conductivity of Graphite Parts also make them play an important role in fuel cells.

Scenario analysis of Graphite Parts in GDL applications

In the GDL scenario of fuel cells, Graphite Parts are mainly used in the following aspects: electrode support, gas diffusion, current collection and conduction, etc. Specifically, the excellent electrical conductivity of Graphite Parts makes them outstanding in current collection and conduction; their good gas diffusion performance ensures the uniform distribution of reaction gas, thus improving the reaction efficiency of fuel cells. In addition, the high porosity and low density of Graphite Parts also help to reduce the internal resistance of the cell and improve the overall performance of the cell.

Advantages and Challenges in Practical Applications

In practical applications, the advantages of Graphite Parts are mainly reflected in its high performance, low cost and sustainability. However, there are also some challenges, such as complex preparation process and performance optimization. In order to give full play to the advantages of Graphite Parts in fuel cells, it is necessary to continuously research and develop new technologies, optimize the preparation process, and improve the performance of Graphite Parts.
