Which outcome limits current production rate within a fuel cell?

💡 Explanation

Ion transport limitation reduces ion supply, causing lower fuel cell current output because overpotential increases therefore lowers the rate; rather than variations due to area, concentration, or simple temperature limits which aren't the primary factor.
