A mechanical compressor is feasible for high-power applications. However, for low-power applications (less than 200 bar), an electrochemical hydrogen compressor (EHC) is more efficient, since the irreversible energy losses (I2R, power losses) increase with the applied current density. The devices involved in the so-called proton exchange membrane technology, including EHC, are governed by thermodynamic-electrochemical principles, so it is important to understand these concepts. Based on the above, the main objective of this chapter is to provide the most relevant aspects of EHC systems.

Abstract
A mechanical compressor is feasible for high-power applications. However, for low-power applications (less than 200 bar), an electrochemical hydrogen compressor (EHC) is more efficient, since the irreversible energy losses (I2R, power losses) increase with the applied current density. The devices involved in the so-called proton exchange membrane technology, including EHC, are governed by thermodynamic-electrochemical principles, so it is important to understand these concepts. Based on the above, the main objective of this chapter is to provide the most relevant aspects of EHC systems.File in questo prodotto:
