This investigation provides a critical analysis of the development of PEM fuel cells and related research with specific focus on the membrane material. The catalytic membrane is the most important component of the PEMFC giving rise to the need for the use of efficient, durable and cheap material to reduce the overall cost of the fuel cell. In this work, the need for materials other than Nafion to be used as PEM membranes is established and a case for the use of composite membranes material in fuel cells is made. Composite membranes increase the cell voltage by up to 11% even at high cell operating temperature of 95°C. They also increase the overall performance of the cell by up to 17% when dry hydrogen is utilised.Non-fluorinated membranes are also suitable for use in fuel cells for portable applications but they are very expensive and less conductive. Partially fluorinated membranes have good mechanical stability but expensive. The fluorinated membrane has high stability under oxidation and reduction conditions. Unfortunately, they only reach their optimum performance at ACCEPTED MANUSCRIPT 1 temperatures below 100°C which makes them of limited use in PEM fuel cells application at higher temperatures.

Summary An accurate assessment of the utilization of a catalyst for fuel cells is beneficial for guiding the optimization of working conditions and adjustment of parameters. In this study, a composite model containing the numerical model of catalyst layers and improved support vector machine (SVM) is proposed to predict the catalyst utilization. The effectiveness factor of the field of catalytic reaction engineering is introduced into the numerical model. The adaptive learning factor and the differential evolution strategy are introduced to improve the ability of generalization and robustness of the distinguishing method in the SVM. The results indicate that the radial basis function is well‐suited as the kernel function of the SVM, and the accuracy of the prediction in the anode and cathode can be increased up to 99.31% and 99.65%, respectively. The increasing transfer coefficient leads to an enhancement of the catalytic reaction, and the particle size of the catalyst impacts the catalytic reaction mainly by changing the pattern of internal diffusion. Pressure has little impact on the Knudsen diffusion.

Summary Over the years, research focused has been on the development of active and stable catalysts for hydrogen (H2) production by steam methane reforming (SMR). However, there is less attention on the individual and interaction effect of key process parameters that influence the catalytic performance of such catalysts and how to optimize them. The main objective of this study is to investigate the individual and interaction effects of key parameters such as methane partial pressure ( PCH4true) (10‐30 kPa), steam partial pressure ( PH2normalO()gtrue) (10‐30 kPa), and reaction temperature (T) (750‐850°C) on H2 yield and methane (CH4) conversion during SMR using Box‐Behnken experimental design (BBD) and response surface methodology. The H2 production was catalyzed using Ni/LSCF prepared by wet impregnation method. The evaluation of the Ni/LSCF using different instrument techniques revealed that the catalyst exhibited excellent physicochemical properties suitable for SMR. Response surface models showing the individual and interaction effect of each of the parameters on the H2 yield and CH4 conversion were obtained using the set of data obtained from the BBD matrix. The three parameters were found to have significant effects on the H2 yield and CH4 conversion. At the highest desirability of 0.8994, maximum H2 yield and CH4 conversion of 89.77% and 89.01%, respectively, were obtained at optimum conditions of 30 kPa, 28.86 kPa, and 850°C for PCH4, PH2normalO()g, and temperature, respectively. The predicted values of the responses from the response surface models were found to be in good agreement with the experimental values. At optimum conditions, the catalyst was found to be stable up to 390 minutes with time on stream. The characterization of the used catalyst using thermogravimetric analysis, scanning electron microscopy, energy‐dispersive X‐ray spectroscopy, and transmission electron microscopy showed some evidence deposition of a small amount of carbon on the catalyst surface.
