摘要: A one-dimensional mathematical model of gas-diffusion electrodes for oxygen reduction is presented to investigate the effect gas composition and mass-transport limitation on current-potential curve. simple explicit analytical solution has been obtained, which works well conditions relatively far from limiting current situation. In proximity this basic be slightly modified an cannot found. Nevertheless, form equations remains simple, making possible direct easy identification parameters electrode. The proposed models have compared favorably with experimental data results a more complex electrode model, developed by other authors. addition, they used as tool estimate gradual aging air
