A wind power generation system including a steel tower and a wind power generator is provided. The wind power generation system may include: a plurality of foundations; a steel tower; a wind power generator; and a support structure supporting the wind power generator. The steel tower may include a plurality of main column members extending upward from base ends fixed to the foundations. At least a portion of the support structure is fixed to at least one of the plurality of foundations without intervention of the plurality of main column members.

Wind power generation system

An object of the present disclosure is to provide a method for manufacturing a fuel cell that ensures developing a high adhesive strength to a separator. One aspect of an embodiment is a method for manufacturing a fuel cell where a pair of separators are mutually bonded with a sealing member. The sealing member includes a thermoplastic resin containing a crystalline polymer as an adhesive layer. The method for manufacturing the fuel cell includes: preparing a stack structure in which the sealing member is disposed between the pair of separators; heating the stack structure at a melting point or higher of the thermoplastic resin; after the heating, holding the stack structure in a temperature range of &#xb1;10&#xb0; C. of a crystallization temperature of the thermoplastic resin to promote a crystallization of the thermoplastic resin; and after the holding, further cooling the stack structure.

Method for manufacturing fuel cell and fuel cell

Provided is a method for manufacturing a fuel cell stack that can manufacture the fuel cell stack efficiently, can improve the precision for joining and can improve the power generation efficiency. The method for manufacturing a fuel cell stack repeatedly stacks a separator, an electrode assembly and a separator in this order in accordance with the laminated structure of the fuel cell stack to be manufactured to manufacture the fuel cell stack. When the electrode assembly is stacked on the separator, the method pressurizes the electrode assembly stacked on the separator and applies laser light to the electrode assembly to join the resin frame of the electrode assembly to the separator. When the separator is stacked on the electrode assembly, the method pressurizes the separator stacked on the electrode assembly and applies laser light to the separator to join the separator to the resin frame of the electrode assembly.
