Inverter and fuel cell

How does a fuel cell inverter work?

The inverter system must convert the fuel cell''s output while accommodating inevitable changes in load and the response time of the fuel cells. The dc output of the cells varies with their load and age and with a polarization curve that is a function of the electrochemistry.

Why is a fuel cell inverter so difficult to convert?

Still, you are dealing with a relatively low-voltage/high-current dc source, which makes it difficult to achieve electrical-conversion efficiency, especially over a wide load range. The inverter system must convert the fuel cell''s output while accommodating inevitable changes in load and the response time of the fuel cells.

Can a DC/AC inverter be used for a fuel cell system?

For the 100kW fuel cell system, a 120kW power converter was selected. However, most commercially available grid-tie DC/AC inverters are not directly applicable to fuel cells due to their incorporation of specific features for maximizing power output from a variable solar input.

Are high power grid-tied inverters suitable for fuel cell systems?

Commercially available high power grid-tied inverters are not suitable for fuel cell systems as they are primarily designed for photovoltaic (PV) systems. These inverters are designed to maximize solar power under varying insolation conditions.
