“…The increase of proton conductivity with increase temperature tends to electrochemical reaction occur faster, the enhanced of water production, and hydration process become much better, thus less resistance of membrane to ion is obtained. Therefore, the proton conductivity increases with increase in temperature [29]. The CS/PWA-MMT/Sil 10% membrane shows the highest proton conductivity 19.15 x 10 -3 S.cm -1 at 80°C.…”

“…Since the hydrolysis reaction of imide rings is reversible 80 and the main chain of polyimide may be reduced in case of close distance between the units 81 , the increase in the degree of crosslinking of the macromolecules facilitates the retention of frame and self-recovery of chains 82 . SPI with a higher degree of crosslinking can sorb more water with less degree of hydrolytic degradation 81,[83][84][85] , which, in turn, increases the proton conductivity 86 .…”

Review is dedicated to discussion of different types of proton-exchange membranes used in fuel cells (FC). One of the most promising electrolytes is polymer electrolyte membrane (PEM). In recent years, researchers pay great attention to various non-fluorinated or partially fluorinated hydrocarbon polymers, which may become a real alternative to Nafion. Typical examples are sulfonated polyetheretherketones, polyarylene ethers, polysulphones, polyimides. A class of polyimides-based hydrocarbon proton-exchange membranes is separately considered as promising for widespread use in fuel cell, such membranes are of interest for our further experimental development.

“…It can be noted that there are orders of magnitude difference in the degree of influence of different parameters on the performance of PEMFC [17][18][19]. Ghasabehi et al [20] compared the effects of different operating parameters on the output power of fuel cells, then found the most effective cathode stoichiometric factor.…”

As a highly nonlinear system, the performance of proton exchange membrane fuel cell (PEMFC) is controlled by various parameters. If the effects of all parameters are considered during the performance optimization, low working efficiency and waste of resources will be caused. The development of sensitivity analysis for parameters can not only exclude the parameters which have slight effects on the system, but also provide the reasonable setting ranges of boundary values for simulation of performance optimization. Therefore, sensitivity analysis of parameters is considered as one of the methods to optimize the fuel cell performance. According to the actual operating conditions of PEMFC, the fluctuation ranges of seven sets of parameters affecting the output performance of PEMFC are determined, namely cell operating temperature, anode/cathode temperature, anode/cathode pressure, and anode/cathode mass flow rate. Then, the control variable method is used to qualitatively analyze the sensitivity of main parameters and combines with the Monte Carlo method to obtain the sensitivity indexes of the insensitive parameters under the specified current density. The results indicate that among these parameters, the working temperature of the fuel cell is the most sensitive to the output performance under all working conditions, whereas the inlet temperature is the least sensitive within the range of deviation. Moreover, the cloud maps of water content distribution under the fluctuation of three more sensitive parameters are compared; the results verify the simulated data and further reveal the reasons for performance changes. The workload of PEMFC performance optimization will be reduced based on the obtained results.
