Abstract: A battery module includes at least two cell assemblies, a module housing having an upper cover formed by a top portion and a first side portion extending downward from a first side edge of the top portion, a first gas passage formed between the first side portion of the upper cover and a first side of the at least two cell assemblies for circulation of gas generated from the at least two cell assemblies, and a flame retardant plate in the first gas passage and extending between the at least two cell assemblies and the module housing, wherein the first side portion of the upper cover is coupled to the flame retardant plate.

Abstract: The present invention relates to an electrolyzer for producing sodium hypochlorite by electrolyzing brine such as salt water or seawater and the like, and more specifically to a horizontal non-membrane type electrolyzer of a new structure which can maintain a constant interval among electrode plates without using a welding means or an adhering means on the inside of a housing by including a separator for dividing an inner space of a hollow type housing into a plurality of electrode chambers; the electrode plates which are arranged in parallel to each other in the constant interval within a rectangular space part of the separator; and a fixing bar for fixing the separator to an inner wall of the housing.
