1. A modular electrolyzer system, comprising:
a plurality of generator modules, each of the plurality of generator modules including electrolyzer cells disposed in a hotbox, the electrolyzer cells configured to generate a hydrogen product by electrolyzing steam provided to the electrolyzer cells; and
hydrogen product piping configured to receive the hydrogen product from hydrogen outlet connections of the plurality of generator modules and to inhibit the backflow of a hydrogen product condensate to the plurality of generator modules,
wherein the hydrogen product piping extends adjacent to ventilation modules of the generator modules, and the hydrogen piping is configured to be heated by exhaust outputs of the ventilation modules to inhibit formation of the hydrogen product condensate.
