Estimation by Volt-Ampere Method of Fuel Battery Efficiency Based on Proton-Exchange Membrane

It is expedient to associate the reliability and uninterrupted performance of transport operations in agriculture in the near future with the promising transition to energy systems based on fuel cells. The increase in energy efficiency is associated with the improvement of the characteristics of fuel cells and power plants based on them. One of the most significant limiting factors is the need to take into account the diverse processes arising in the study of fuel cells based on a proton-exchange membrane in the entire operating range, which leads to cumbersome theoretical calculations. In this regard, the problem of predicting the average value of the energy efficiency of fuel cells at a given load is urgent. The proposed method for evaluating the study of changes in the average energy efficiency of fuel cells from a given load based on the construction of current-voltage characteristics makes it possible to estimate with sufficient reliability the instantaneous and average efficiency as a function of the state of the output signal in a given load mode. On the basis of the conducted experimental studies, it was found that with an increase in the load, the average efficiency of the fuel cell decreases. The main ways to increase the efficiency of a fuel cell is to use a combined compound of fuel cells, and to ensure the supply of the necessary reagents.
