Bipolar Plates For Fuel Cells
In hydrogen fuel cells,electrode plates play a crucial role. Firstly, the electrode plate directly affects the progress of electrochemical reactions by transferring electrons and promoting ion transport. Specifically, hydrogen gas is decomposed into hydrogen ions and electrons at the anode (negative electrode). Hydrogen ions reach the cathode through the electrolyte, while electrons cannot pass through the electrolyte and can only form current through external circuits.
In addition, the electrode plate also serves to separate the gas, provide a reaction interface, and conduct current. It not only supports the membrane electrode, ensuring that hydrogen and oxygen can be evenly distributed and fully reacted, but also collects current, completes heat dissipation, and discharges gas from the battery. Therefore, the design and material selection of electrode plates are crucial for achieving more efficient and controllable electrochemical reaction processes.
