                      in various industrial applications, but high production
                      costs continue to hinder its market penetration today.
                      Better competitiveness is linked to lower investment costs
                      and higher efficiency of the conversion technologies, among
                      which polymer electrolyte membrane electrolysis seems to be
                      attractive. Although new manufacturing techniques and
                      materials can help achieve these goals, a less frequently
                      investigated approach is the optimization of the design
                      point and operating strategy of electrolyzers. This means in
                      particular that the questions of how often a system should
                      be operated and which cell voltage should be applied must be
                      answered. As existing techno-economic models feature gaps,
                      which means that these questions cannot be adequately
                      answered, a modified model is introduced here. In this
                      model, different technical parameters are implemented and
                      correlated to each other in order to simulate the lowest
                      possible levelized cost of hydrogen and extract the required
                      designs and strategies from this. In each case investigated,
                      the recommended cost-based cell voltage that should be
                      applied to the system is surprisingly low compared to the
                      assumptions made in previous publications. Depending on the
                      case, the cell voltage is in a range between 1.6 V and 1.8
                      V, with an annual operation of 2000–8000 h. The wide range
                      of results clearly indicate how individual the design and
                      operation must be, but with efficiency gains of several
                      percent, the effect of optimization will be indispensable in
                      the future.},
