Use of Novel Reinforced Cation Exchange Membranes for Microbial Fuel Cells

Harmonic analysis based method for linearity assessment and noise quantification in electrochemical impedance spectroscopy measurements: Theoretical formulation and experimental validation for Tafelian systems

“…Introducing assumptions (11) and (12) in equation (10), and particularizing the obtained expression for a perturbation frequency of , the following expression is obtained:…”

“…This feature makes the technique suitable for a large range of applications. This explains why it has been widely used in electrochemical related fields as fuel cells [6][7][8][9][10][11][12], batteries [13][14][15][16][17][18], corrosion [19][20][21][22][23], coatings [24][25][26], electrochemical sensors [27][28] and supercapacitors [29][30][31][32]. This electrochemical technique has also been used in fields that are not traditionally related to electrochemistry as biochemical assays [33][34][35][36], oncology [37][38][39] and immunology [40][41], amongst others.…”

Design of gel electrolytes for electrochemical studies on metal surfaces with complex geometry

“…Polymer gel electrolytes have been extensively studied due to their potential use in electrochemical devices, such as batteries [7,8], solar cells [9,10], fuel cells [11][12][13] and electrochromic devices [14,15]. Other authors have proposed a portable corrosion cell based on the use of agar as a gelling agent to perform non-destructive, in-situ electrochemical measurements for application in cultural heritage studies [16,17].…”

“…Agar is a complex mixture of polysaccharides found in the cell matrix of red algae as Rhodophyta (Gracilaria, Gelidium and Pterocladia) [11,12], comprising two major components, commonly known as agarose and agaropectin. Agarose is a neutral polysaccharide with a linear structure of repeating units of agarobiose formed by 1,3linked-D-galactose and 1,4-linked 3,6-anhydro-L-galactose units [13,14]. The type, pattern, and degree of substitution, as well as the molecular weight, determine the gelling properties of agar [22].…”

Performance of Cathode Catalysts for Bio-Electricity from Paper Recycling, Wastewater-Fed, Microbial Fuel Cells

“…The CE for MWCNT, FePc/KB and MWCNT/FePc coated electrodes was 10.64%, 7.44% and 8.37% respectively. The electrochemical activity was enhanced by the hybrid bacterial attachment over the electrode 36 . COD removal efficiency increased with increase in initial concentration 37 .…”
