- 4624 Experimental Study on Crossover in Direct Methanol Fuel Cell Stack
抄録
Methanol crossover found in the direct methanol fuel cell was experimentally investigated with a 15-cell stack. Fuel cell performance, fuel crossover quantity and stack temperature were measured while fuel concentration was varied between 1-5%. The results showed that the crossover increased as the fuel concentration increased with an increase of stack temperature. The stack temperature rise resulted in improvement of I-V characteristics and promotion of methanol vaporization. The results also showed that the current efficiency reached to 86% at the maximum in case of 1% of fuel concentration, however, it fell to as low as 40% at the maximum for 5% of fuel concentration. It was also confirmed that much water was consumed to transfer protons from the anode to the cathode.
