A configuration of an electrolyte membrane for a fuel cell is provided, which can be sealed reliably and easily between the separators. The coating includes at least one metal layer, such as a metallic silver layer. The lid may include an elevated rim in-set and about the periphery thereof with a dome within a recess defined by the elevated rim. In the layer of electrode material, the gate electrodes for the transistors of the second type are formed. The decoder is configured to determine a non-zero filter strength value based on the obtained coded block type of the second block and the determination of whether the second block has non-zero transform coefficient information, and is configured to remove the blocking phenomenon in the first block according to the filter strength value.
