Power sources involving ~ 300W PEMFC fuel cell stacks cooled by different media

The paper presents a brief analysis of the potential use of hydrogen-oxygen low-temperature fuel cells with proton-exchange membrane fuel-cell stacks as power sources for the construction of drive units powering unmanned aerial vehicles. Hydrogen storage methods are discussed. Characteristics of selected aspects of monitoring the electrical and non-electrical operating parameters of a drive unit with fuel cells were investigated, with respect to the fuel cell, fuel-cell cooling system, and gas reagent supplying the system with hydrogen and air. Hydrogen fuel consumption for the production of electricity and purification, or so-called purge, was analysed. Based on the results of laboratory tests of the parameters of a generator with fuel cells, an exemplary method of monitoring operating parameters and controlling power sources involving fuel cells is proposed.

In Situ and Operando Characterization of Proton Exchange Membrane Fuel Cells

For proton-exchange-membrane fuel cells (PEMFCs) to become a mainstream energy source, significant improvements in their performance, durability, and efficiency are necessary. To improve their durability, there must be a solid understanding of how the structural and electrochemical processes are affected during operation to propose mitigation strategies. To this aim, in situ and operando characterization techniques locally identify structural and electrochemical processes, which cannot be captured using conventional techniques. Nevertheless, linking these properties in the same geometric area has been challenging due to its inherent limitations, such as sample size and imaging resolution. This has created a knowledge gap in structure-to-electrochemical performance relationships as operation and degradation unevenly affect different areas of the cell.
