Description

  The present invention relates to a fuel cell having a humidity detection device, in particular capable of detecting humidity.

 The fuel cell currently in use is a fuel cell system that generates an electric power by causing an electrochemical reaction mainly using a fuel fluid containing a large amount of hydrogen (such as methyl alcohol) and an oxygen fuel fluid. There is a need to inform the user when there is a shortage of fluid or when the fuel fluid should be replenished, and improvements in technology have led to improvements in fuel cell efficiency, which also introduces inductive problems.

 In response to the above, one of the problems that fuel cells induce is humidity change, and the power generator in the fuel cell has several circuit boards stacked on top of each other.
