AB  - Microbial electrochemical conversion of CO(2) to value-added products needs 
      effectual biocathodes. In this study, three different working electrodes 
      (biocathode) namely carbon cloth (CC, MES1), stainless steel mesh (SS, MES2) and 
      hybrid electrode (CC + SS, MES3) were evaluated in membrane-less single-chambered 
      Microbial electrosynthesis systems (MESs). Performance of MES was assessed by 
      total volatile fatty acids (VFA) productivity and, reductive current generations 
      upon continuous poised potential (-0.4 V vs. Ag/AgCl (3.5 M KCl)). MES3 showed 
      higher VFA synthesis (CC + SS; 1.4 g VFA/L), followed by MES1 (CC; 1.1 g VFA/L) 
      and MES2 (SS; 0.8 g VFA/L) with corresponding reductive current generation of 
      -1.13 mA, -2.74 mA and -0.39 mA. Electro-kinetics revealed the biocathode 
      efficacy towards enhanced electrotrophy with confined electron losses by 
      regulating electron flux in the system. The study infers the potential of hybrid 
      electrode as an efficient biocathode for the reduction of CO(2) to VFA synthesis.
