Abstract

In this paper, a novel power generation cum storage system employing reversible solid oxide fuel cell (RSOFC) has been proposed. The RSOFC is integrated with solar PV/T system that also includes parabolic trough solar collectors (PTSC). The RSOFC unit operates in steam electrolyser mode (during day time) and in fuel cell mode (during night time). The electrochemical model is developed for a proton conducting reversible solid oxide fuel cell (RSOFC-H) and its performance analysis is done both in fuel cell mode and electrolysis mode of operation. A comparative performance analysis has also been done between conventional oxide ion conducting reversible SOFC (RSOFC-O) and proton conducting RSOFC-H for suitably chosen range of current density to cover both the cells' common operating range (500 A/m2 to 5000A/m2). Computational simulation model for the integrated plant has been developed and the simulated performance analyzed both using energy and exergy approaches. The results suggest that the solar-integrated system can yield an overall solar-to-gas conversion efficiency of about 18% in electrolysis mode while in fuel cell mode the conversion efficiency (gas-to-power) would be about 40%.
