Comment on "A strategy of estimating fuel concentration in a direct liquid-feed fuel cell system" [YJ Chiu, HC Lien, journal of Power Sources 159 (2006) 1162-1168]
The strategy for estimating the methanol concentration provided by Chiu and Lien [Y.J. Chiu, H.C. Lien, journal of Power Sources 159 (2006) 1162-1168] overlooks the performance degradation (PD) of a direct methanol fuel cell (DMFC). In addition, the method may not be suitable in practice.
