Abstract: Systems and methods are provided for water electrolysis. The system includes an ion exchange membrane, a first electrode catalyst layer on a first side of the ion exchange membrane, wherein the first electrode catalyst layer includes a transition metal-phosphorus-based compound on the first side of the ion exchange membrane, and a second electrode catalyst layer on a second side of the ion exchange membrane opposite the first side. In some embodiments, the first electrode catalyst layer is electroplated to the first side of the ion exchange membrane. In some embodiments, the second electrode catalyst layer includes a compound comprising the same transition metal as the first electrode catalyst layer.
