A series of sulfonated poly(arylene ether sulfone) (SPAES) membranes with different of degree of sulfonation (DS) are prepared for microbial fuel cell (MFC) applications. The performance of the MFCs equipped with SPAES membranes is investigated in details. During the start-up stage, the need time of reaching stable state and maximum anodic potential for the MFCs decreases with the increase of DS of the SPAES membranes. However, the power density of MFCs with SPAES(5-5), SPAES(4-6), SPAES(3-7) is very close after 14 days, which should be resulted from the combining effects of the exchange of H+ to Na+ in the SPAES membrane and the fouling of the membranes. The DS affects the anti-fouling activity of SPAES membranes, and higher DS leads to lower anti-fouling activity. The MFC equipped with SPAES(3-7) membrane (DS=30%, IEC=1.31 mmol g-1) is considered the better choice for the long-term operation.
