Description
technical field [0001] The invention belongs to the technical field of performance measurement of a reversible solid oxide fuel cell, and in particular relates to a measurement system and method for a reversible solid oxide fuel cell. Background technique [0002] Reversible solid oxide fuel cells and accessories (including gas control and circuit parts) are the physical basic components for building distributed power generation networks, and are also key equipment for energy storage. However, due to the slow gas transport in the porous electrode, the dynamic performance of the reversible solid oxide fuel cell will be affected when the state of the reversible solid oxide fuel cell is switched between the electrolysis and hydrogen production modes. In addition, a major advantage of solid oxide fuel cells over proton exchange membrane fuel cells is that they support a variety of fuel gases, including hydrogen, carbon monoxide, and methane. At the same time, in electrolysis mod...
