【 摘 要 】

In this paper, a novel power generation cum storage system employing reversible solid oxide fuel cell (RSOFC) has been proposed and modelled. The RSOFC is integrated with solar PV/T system. Here only the electrochemical modelling of the fuel cell unit has been presented and analysed thermodynamically. The RSOFC unit operates in steam electrolyser mode (during day time) as well as in fuel cell mode (during night time). The electrochemical model has been developed by using Engineering Equation Solver. Performance of RSOFC unit has been investigated under varying operating parameters viz. applied current density and operating cell temperature. For electrolyser mode of operation maximum efficiency is found to be 93% at a current density (J) 8000 A/m2 and at cell temperature (Tcell) 1273K. Maximum efficiency during fuel cell mode of operation is found to be 77% at cell temperature 1073K and at current density 500 A/m2.
