The invention aromatized used as energy for a portable non-humidified proton exchange membrane fragrance radiate thermal energy having a high-temperature water is generated as a reaction by-product of the oxygen and hydrogen to be, from a more particularly to a fuel cell stack of the fuel cell to be configured on the proton exchange membrane fuel cell such that the fragrance during operation of the fuel cell occurs. According to the invention, simply by removing water generated as a by-product of the electrochemical reaction of the fuel cell as well as to protect the portable device and protect the human body from danger such as a burn, pleasant to ensure dissipation is using a given flavor there is an advantage to keep the working environment.
