Researchers interest in using fuel cells as a power source has grown because fuel cells are environmentally friendly. However, fuel cells still present challenges due to their performance and cost. This limits the commercialization of fuel cell systems, particularly in liquid fuel cells. One of the major obstacles is the Nafion membrane. The Nafion membrane is extremely expensive and causes the "fuel crossover phenomenon." Therefore, researchers have proposed a membrane-less fuel cell that eliminates the need of a membrane in the system mainly in micro fuel cells. Membrane-less fuel cell has shown an improvement on power density by approximately 12% compared with conventional type of proton electrolyte membrane fuel cell. However, there still a lack of information on system design and performance. Therefore, the main objective of this review is to present an extensive study focusing on the geometrical system design and performance of a membrane-less fuel cell system. It also presents the different types of membrane-less fuel cell systems. Lastly, it highlights the current problems and potentials to improve the performance of the system. Finally, it is observed that the cost of a membrane fuel cell can be reduced by 20% to 40% compared with the conventional type of fuel cell.

“…This is in addition to the high extent of proteins in the yeast cell membrane, which is an important characteristic of electroactive species [4,6]. Yeast cells also have a thick (100-200 nm) cell wall constructed of polysaccharides and proteins [43,52]. Yeast cytochromes are located in the mitochondria, and transmembrane proteins (tPMETs) are Yeast as a Biocatalyst in Microbial Fuel Cell http://dx.doi.org/10.5772/intechopen.70402located in the cell membrane, which are enclosed by the cell wall.…”

“…The electron transfer of S. cerevisiae based MFC was enhanced by immobilizing S. cerevisiae on carbon nanotube (yeast/CNT) to be used as a catalyst in a membrane-less MFC [43]. The effect of the entrapping polymer (EP) and cross-linker (glutaraldehyde, GA) addition on the performance and stability of the MFC using laccase as cathodic catalyst was investigated.…”
