Mathematical models of direct internal reforming solid oxide fuel cell (DIR-SOFC) fueled by methane are developed using COMSOL V R software. The benefits of inserting Ni-catalyst rod in the middle of tubular-SOFC are simulated and compared to conventional DIR-SOFC. It reveals that DIR-SOFC with inserted catalyst provides smoother temperature gradient along the system and gains higher power density and electrochemical efficiency with less carbon deposition. Sensitivity analyses are performed. By increasing inlet fuel flow rate, the temperature gradient and power density improve, but less electrical efficiency with higher carbon deposition is predicted. The feed with low inlet steam/carbon ratio enhances good system performances but also results in high potential for carbon formation; this gains great benefit of DIR-SOFC with inserted catalyst because the rate of carbon deposition is remarkably low. Compared between counter-and co-flow patterns, the latter provides smoother temperature distribution with higher efficiency; thus, it is the better option for practical applications.

“…The utilization of renewable sources such as biomass or biogas can reduce fossil fuel dependency and avail to reduce the CO 2 emissions, as they are carbon neutral. Biomass gasification to engender hydrogen and/or syngas (H 2 +CO) has been considered as a promising method for fuel conversion and downstream integration with high temperature fuel cells such as SOFCs [3][4].…”

Abstract-This research work utilizes the computational approach for dynamic modelling solid oxide fuel cell. Dependency of the efficiency of the stacked fuel cell is estimated for varying number of fuel cell. DC voltage generated by the fuel cell was computed and utilized for converting it into three phase AC voltage via IGBT based inverter. Increased in the trend line behaviour with respect to increasing number of fuel cell stack was observed. The power delivered to the load is affected by the type of load connected to the power system. At 250 stack level of the fuel cell, power delivered to RLC and RL connected load in same. Also various concentration levels of the hydrogen, oxygen, and water are also estimated.
