Yes, using carbon paper as an electron-permeable membrane in a galvanic cell can be a practical and cost-effective solution. Carbon paper is commonly used in fuel cells and other electrochemical devices for its ability to conduct electricity while providing structural support and a porous surface that allows for the flow of reactants and electrolytes.
Benefits of Using Carbon Paper in a Galvanic Cell:
Electrical Conductivity: Carbon paper is a good conductor of electricity, allowing electrons to flow freely between the electrodes, which is essential for the operation of a galvanic cell.
Porosity: The porous nature of carbon paper allows ions in the electrolyte to pass through while maintaining electron flow, enabling the electrochemical reactions necessary for the galvanic cell to function.
Chemical Stability: Carbon paper is chemically stable and resistant to corrosion, making it suitable for use in various electrolytes and under different operating conditions.
Cost-Effectiveness: Carbon paper is relatively inexpensive compared to other specialized conductive materials, making it a practical choice for experiments, prototypes, or low-cost applications.
Application in a Galvanic Cell:
Electron Transport: In a galvanic cell, carbon paper can serve as an electrode or as part of the electrode assembly, facilitating electron transfer from the anode to the cathode through an external circuit.
Ion Exchange: While carbon paper allows for the passage of electrons, it also has enough porosity to allow for the movement of ions in the electrolyte, which is critical for maintaining charge balance and enabling continuous operation of the cell.
Considerations:
Thickness and Density: The thickness and density of the carbon paper will affect its conductivity and the ease with which ions can move through it. Thinner carbon paper with higher porosity might be more effective for certain applications.
Contact Resistance: Ensure good contact between the carbon paper and the other components of the galvanic cell to minimize resistance and improve efficiency.
Example Applications:
Fuel Cells: Carbon paper is widely used as a gas diffusion layer (GDL) in fuel cells, where it facilitates the distribution of gases to the catalyst layers while conducting electrons.
Batteries: It can also be used in batteries as a current collector or a part of the electrode structure, particularly in lithium-ion and metal-air batteries.
In summary, carbon paper is indeed a suitable and cost-effective material for use as an electron-permeable membrane in a galvanic cell, offering a good balance between conductivity, porosity, and stability.
Also, according to Arie Melis deGeus patent electron membrane can be liquid, gel or powder … it is pretty obvious that a powder needs a support that can be a thin or thick paper as a permeable substrate.
