To make a fuel container not damage the performance of a fuel cell by forming the structure preventing mixing of metallic ions into contained fuel for the fuel cell and to ensure the durability of energizing members.

The container for the fuel cell is equipped with a container body 2 having sealing structure and a valve mechanism 5 opening and closing the supply of fuel, and all constituting members coming into contact with fuel are formed of non-metallic materials. The energizing members of the valve mechanism 5 are constituted with a resin spring 54 having a supporting base part 15 at one end holding an attitude; a contact part 16 at the other end; and a turning up-shaped plate spring deforming part 17 connecting both parts. The fuel is methanol and pure water, ethanol and pure water, pure methanol, or pure ethanol, and is suitable for the fuel for a solid polymer fuel cell.
