Benefits of technology

The technical effect of this patented technology is that it allows for better control over the amount of hydrogen supplied during startup of a fuel cell system by adjusting the direction of hydrogen supply from one side to another. This helps improve the performance and lifespan of the fuel cells while reducing their potential negative impact on the environment.

Problems solved by technology

This patent describes a method for controlling the hydrogen concentration in a fuel cell stack in response to startup conditions such as starting up the fuel cell stack under specific conditions. However, this can lead to unstable performance and increased emissions when the hydrogen purification process is completed too early.
