    • Advances in alkaline water electrolyzers: a review 

      David, Martín Rafael; Ocampo-Martínez, Carlos; Sánchez Peña, Ricardo Salvador (Elsevier, 2019)
      Article
      Open Access
      The renewed concern for the care of the environment has led to lower emissions of greenhouse gases without sacrificing modern comforts. Widespread proposal focuses on energy produced from renewable sources and its subsequent ...
    • Dynamic modelling of alkaline self-pressurized electrolyzers: a phenomenological-based semiphysical approach 

      David, Martín Rafael; Alvarez, Hernan; Ocampo-Martínez, Carlos; Sánchez Peña, Ricardo Salvador (2020-01-01)
      Article
      Open Access
      This paper proposes a phenomenological based semiphysical model (PBSM) for a self-pressurized alkaline electrolyzer. The model, based on mass and energy balances, represents the dynamic behaviour of hydrogen and oxygen ...
    • H2 purity control for highpressure alkaline electrolyzers 

      David, Martín Rafael; Bianchi, Fernando Daniel; Ocampo-Martínez, Carlos; Sánchez Peña, Ricardo Salvador (Science Press, 2021)
      Conference report
      Open Access
      This paper proposes a control strategy that mitigates the cross contamination of H2 and O2 in a high-pressure alkaline electrolyzer, which consequently increases the supplied gases purity. In order to reduce the diffusion ...
    • Mathematical modelling and advanced control design applied to high-pressure electrolyzers for hydrogen production 

      David, Martín Rafael (2021-11-08)
      Doctoral thesis
      Open Access
      This thesis is mainly dedicated to the study of high-pressure alkaline electrolysis. Alkaline electrolysis is a well established technology and is commercially available. However, the operation at high pressure for dispensing ...
    • Model-based control design for H2 purity regulation in high-pressure alkaline electrolyzers 

      David, Martín Rafael; Bianchi, Fernando Daniel; Ocampo-Martínez, Carlos; Sánchez Peña, Ricardo Salvador (2021-05-01)
      Article
      Restricted access - publisher's policy
      This paper proposes two control strategies that mitigate the cross contamination of H2 and O2 in a high-pressure alkaline electrolyzer, which consequently increases the supplied gases purity: one based on a decoupled PI ...
    • Phenomenological based model of hydrogen production using an alkaline self-pressurized electrolyzer 

      David, Martín Rafael; Alvarez Zapata, Hernán Darío; Ocampo-Martínez, Carlos; Sánchez Peña, Ricardo Salvador (Institute of Electrical and Electronics Engineers (IEEE), 2019)
      Conference report
      Open Access
      The aim of this work is to develop the phenomenological based modeling of a self-pressurized alkaline electrolyser with the objective of predicting the cross-contamination of the gases produced. A proposed model, built in ...
