The discussion centers on the relationship between the maximum power output of a hydrogen-oxygen fuel cell and the gas flow rate at constant pressure and room temperature. Participants explore the concept that, assuming constant efficiency, the maximum power output does indeed vary directly with the flow rate of the gases. The conversation emphasizes the importance of maintaining constant pressure and temperature conditions to accurately assess this relationship. Additionally, there is a mention of a related thread on the electrolysis of water, indicating that some members may have expertise in both areas, although the focus remains on fuel cell dynamics.
