Abstract
A planar fuel cell stack, having generators that generate electricity by an electrochemical reaction of a fuel and an oxidizing agent, the generators arranged on a same plane. A beading unit and a protruding portion are formed on a fastening plate and a separator so as to improve structural stiffness thereof. Accordingly, the constituent elements of the stack are fastened with a substantially uniform conjoining pressure compared to a conventional planar stack, and the thickness of the stack of the present invention can be thinner than that of the conventional planar stack.
