Abstract
The present invention provides a membrane electrode assembly (MEA) which has a high level of power generation performance under a low humidified condition and a high level of production efficiency, and further, a manufacturing method of such an MEA and a fuel cell having such an MEA. The present invention includes forming first electrode catalyst layer, forming polymer electrolyte layeron the first electrode catalyst layerin such a way that a cross sectional surface of the first electrode catalyst layeris also covered with the polymer electrolyte layer, and forming second electrode catalyst layeron the polymer electrolyte layerin such a way that a cross sectional surface of the second electrode catalyst layeris covered with the polymer electrolyte layer
