Example Embodiment
[0037] The following examples further illustrate the technical solutions of the present invention, but are not intended to limit the protection scope of the present invention.
[0038] The cross type MEA fuel cell of the present invention, as attached figure 1 As shown, it includes a space structure MEA1, a diffusion layer (GDL) (3 and 7), a reaction gas flow channel 6, an electrode plate 4, and a water flow channel (2 and 5);
[0039] The space structure MEA can be a tic-tac-toe, cross or honeycomb mesh structure, please refer to the attachment Figure 4 As shown; MEA is arranged in sequence from the center to the two sides according to the proton exchange membrane 8, the catalytic layer 9, and the microporous layer 10. Refer to the attachment image 3 Shown. When the space structure MEA is a well-shaped or honeycomb structure, the reaction gas flow channel not only transports gas but also acts as a plate to conduct current.
[0040] The diffusion layer presents a tubular structure...
