A stack for a fuel cell includes a first collecting plate having a first electric polarity, a second collecting plate having a second electric polarity different from the first electric polarity, and at least one electricity generator located between the collecting plates. The at least one electricity generator is for generating electric energy due to electrochemical reaction between hydrogen and oxygen to be collected by the collecting plates. Coupling members press the at least one electricity generator in an airtight connection between the collecting plates. A terminal member protrudes from the second collecting plate and is electrically connected to the first collecting plate and insulated from the second collecting plate, such that the terminal member is used as a first terminal having the first polarity. The second collecting plate or a second terminal member may also be used as a second terminal having the second polarity.
