       7 . A portable device according to  claim 1 , wherein the outer wall has a buffer member located between the fuel cell and the outer wall. 
   
   
       8 . A portable device according to  claim 1 , further comprising a grip portion that can be held by a user,
 wherein the proton conducting film is disposed along the grip portion.   
   
   
       9 . A portable device according to  claim 1 , further comprising a lid member that makes a part of the device housing openable and closable,
 wherein the proton conducting film is disposed along the lid member.   
   
   
       10 . A portable device according to  claim 1 , further comprising a substrate therein,
 wherein at least a part of the proton conducting film is disposed between the outer wall of the device housing and the substrate.   
   
   
       11 . A portable device according to  claim 10 , wherein the proton conducting film is folded back so as to be disposed along both sides of the substrate. 
   
   
       12 . A portable device according to  claim 10 , wherein the substrate is a circuit board constituting auxiliary light emitting portion. 
   
   
       13 . A portable device according to  claim 1 , further comprising reaction suppressing portion for suppressing an electrochemical reaction in the fuel cell provided in the portable device. 
   
   
       14 . A portable device according to  claim 13 , wherein the reaction suppressing portion suppresses the electrochemical reaction by adjusting a voltage applied to the fuel cell. 
   
   
       15 . A case for a portable device capable of accommodating therein a portable device having a fuel cell as a power source, the case comprising:
 a case housing;   a proton conducting film disposed in the vicinity of a wall body of the case housing integrally with the wall body;   catalyst layers disposed on both sides of the proton conducting film in a thickness direction thereof;   fuel of the fuel cell disposed on one of the catalyst layer sides of the proton conducting film; and   an air chamber disposed on the other of the catalyst layer sides of the proton conducting film for supplying air to the fuel cell.   
   
   
       16 . A case for a portable device according to  claim 15 , wherein the proton conducting film is disposed so as to be folded along the case housing.
