Embodiment 1

[0138] As a polymer electrolyte membrane, it is manufactured as follows [CF 2 CF 2 ] 0 . 812 -[CF 2 -CF(-O-(CF 2 ) 2 -SO 3 H)] 0 . 188 An electrolyte membrane composed of the indicated perfluorocarbon sulfonic acid polymer (hereinafter referred to as "PFSA") was used as a polymer electrolyte membrane.

[0139] (Preparation of Polymer Electrolyte Solution)

[0140] First, precursor particles of the above polymer electrolyte (proton exchange capacity after hydrolysis and acid treatment: 1.4 meq / g) were prepared. Next, the precursor particles were brought into contact with an aqueous solution in which potassium hydroxide (15% by mass) and methanol (50% by mass) were dissolved at 80° C. for 20 hours to perform a hydrolysis treatment. After that, the pellets were immersed in water at 60° C. for 5 hours. Next, the particles immersed in water were immersed in 60° C. 2N hydrochloric acid aqueous solution for 1 hour, and the above treatment was repeated 5 times, and the hydr...

Abstract

The purpose of the invention is to provide a roll-like polyelectrolyte film packaging body, and a manufacturing method of the packaging body, and a packed object. When a roll-like polyelectrolyte film is stored or transported, the packaging body can prevent defects, such as wrinkles or damage, from generation, so that the unqualified rate of the polyelectrolyte film can be reduced. The roll-like polyelectrolyte film packaging body of the invention has a roll core, the roll-like polyelectrolyte film being wound round the roll core, and two protectors arranged at two end surfaces of the roll core. Each protector has a side plate, the size of which is larger than the outer diameter of the roll-like polyelectrolyte film. The side plates of the two protectors arranged at two end surfaces of the core and the core can maintain the roll-like polyelectrolyte film wound round the core in a suspension state.

Description

technical field [0001] The present invention relates to a roll-shaped polymer electrolyte membrane package, a method for producing the same, and a package. Background technique [0002] A fuel cell obtains electrical energy within the cell by an electrochemical reaction originating from a fuel (hydrogen source) and an oxidant (oxygen), which directly converts the chemical energy of the fuel into electrical energy. As a fuel source of the fuel cell, petroleum, natural gas (methane, etc.), methanol, etc. containing hydrogen represented by pure hydrogen are used. [0003] The fuel cell itself generates little noise because it has no mechanical parts, and by continuously supplying fuel and oxidant from the outside, it can theoretically generate electricity semi-permanently. [0004] Electrolytes used in fuel cells are classified into liquid electrolytes and solid electrolytes, among which a battery using a polymer electrolyte membrane as an electrolyte is called a solid polymer...
