Abstract
A fuel cell unit includes a lower case and an upper case. A cell stack of multiple fuel cells is accommodated in the lower case. The upper case is coupled to the lower case. Substrates on which electronic components are implemented are mounted to an inner side of the upper case. A wall extending from a top plate of the upper case is provided between a side plate of the upper case and the substrates. When the upper case is turned, the wall prevents falling dust from adhering to the substrates.

A manufacturing method of a power supply unit, the power supply unit including:
- a lower case in which a fuel cell or a battery is accommodated;
- an upper case containing substrates that are mounted to an inner side of the upper case, electronic components being implemented on the substrates, the upper case being coupled to the lower case;
- and
- a wall extending from a top plate of the upper case, the wall being provided between a side plate of the upper case and the substrates,
- the manufacturing method comprising:
- holding the upper case with the inner side of the upper case facing upward, and fixing the substrates to the upper case;
- turning over the upper case in a height direction after the upper case gets through a state in which the wall is located over the substrates;
- and
- coupling the upper case to the lower case.
