To deconvolute the multistep elementary reactions at both of the electrodes, EIS was measured as a function of temperature (775 \u00b0C\u2013850 \u00b0C), gas compositions, and gas flow rates (50\u2013200 sccm). Concurrently, DRT analysis was employed to resolve frequency-dependent electrode reactions effectively. From the DRT analysis, multistep elementary reactions at fuel and air electrode were separated and corresponded to a transmission line equivalent circuit model with parameters (\n                    <jats:inline-formula>\n                      <jats:tex-math>\n                        \n                      <\/jats:tex-math>\n                      <mml:math xmlns:mml=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" overflow=\"scroll\">\n                        <mml:msub>\n                          <mml:mrow>\n                            <mml:mi>R<\/mml:mi>\n                          <\/mml:mrow>\n                          <mml:mrow>\n                            <mml:mi>s<\/mml:mi>\n                            <mml:mo>,<\/mml:mo>\n                            <mml:mi>e<\/mml:mi>\n                            <mml:mi>l<\/mml:mi>\n                            <mml:mo>.<\/mml:mo>\n                          <\/mml:mrow>\n                        <\/mml:msub>\n                        <mml:mo>,<\/mml:mo>\n                      <\/mml:math>\n                    <\/jats:inline-formula>\n                    <jats:inline-formula>\n                      <jats:tex-math>\n                        \n                      <\/jats:tex-math>\n                      <mml:math xmlns:mml=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" overflow=\"scroll\">\n                        <mml:msub>\n                          <mml:mrow>\n                            <mml:mi>R<\/mml:mi>\n                          <\/mml:mrow>\n                          <mml:mrow>\n                            <mml:mi>p<\/mml:mi>\n                            <mml:mo>,<\/mml:mo>\n                            <mml:mi>e<\/mml:mi>\n                            <mml:mi>l<\/mml:mi>\n                            <mml:mo>.<\/mml:mo>\n                          <\/mml:mrow>\n                        <\/mml:msub>\n                        <mml:mspace width=\".25em\"\/>\n                        <mml:mi>a<\/mml:mi>\n                        <mml:mi>n<\/mml:mi>\n                        <mml:mi>d<\/mml:mi>\n                        <mml:mspace width=\".25em\"\/>\n                        <mml:msub>\n                          <mml:mrow>\n                            <mml:mi>C<\/mml:mi>\n                          <\/mml:mrow>\n                          <mml:mrow>\n                            <mml:mi>p<\/mml:mi>\n                            <mml:mo>,<\/mml:mo>\n                            <mml:mi>e<\/mml:mi>\n                            <mml:mi>l<\/mml:mi>\n                            <mml:mo>.<\/mml:mo>\n                          <\/mml:mrow>\n                        <\/mml:msub>\n                      <\/mml:math>\n                    <\/jats:inline-formula>\n                    ).
