A fuse box is a crucial component in a fuel cell system for several reasons, primarily related to safety, protection, and reliability. A fuse box helps protect the electrical components of the fuel cell system from damage due to excessive current, while also reducing the risk of electrical shock to personnel working with or around the fuel cell system.

In the event of a severe fault, the fuse box can help ensure that the fuel cell system shuts down safely, protecting users from hazardous situations.
