Abstract: Disclosed are an apparatus for manufacturing an electrolyte membrane and a method for manufacturing an electrolyte membrane using the same, which may prevent discoloration of the electrolyte membrane through a controlled drying process of the electrolyte membrane. The electrolyte membrane manufactured by the method of the present invention may not be discolored and performance and durability of fuel cells using the electrolyte membrane may be improved due to uniform drying of the electrolyte membrane during the manufacturing. For example, competitively simultaneous evaporation of solvents in an ionomer composition in the drying process may be prevented.

Abstract: An error correcting circuit receives a codeword including user data and a parity code, and performs an error correction operation on the user data. The circuit includes a first buffer, a decoder, a second buffer and a processor. The first buffer stores the codeword and sequentially outputs pieces of subgroup data obtained by dividing the codeword. The decoder generates pieces of integrity data for each of the pieces of subgroup data received from the first buffer, and performs the error correction operation on the user data using the parity code. The second buffer sequentially stores the pieces of integrity data for each of the pieces of subgroup data. The processor determines whether an error is present in the codeword based on the pieces of integrity data stored in the second buffer when at least one of the pieces of integrity data is updated in the second buffer.
