Review on the Test Method of Water Electrolysis Hydrogen Production System

<div class="section abstract"><div class="htmlview paragraph">The development of hydrogen economy is an effective way to achieve peak carbon emission and carbon neutralization. Therein, the green production of hydrogen is a prerequisite to reach the goal of decarbonization. As an ideal route, water electrolysis has triggered intense responses under the strong support from policies, which further presenting a phenomenon of water electrolysis equipment manufactures competing to enter the market. However, the extensive growth mode is not conducive to a long term healthy development of the water electrolysis hydrogen production market where products can be sold without requiring compulsory inspection or quality inspection process due to the absence of laws and test &amp; evaluation standards. Considering the market status and technology maturity, the main working principles and characteristics of alkaline water electrolysis (AWE) and proton exchange membrane (PEM) hydrogen production systems are summarized, and the test frameworks of the AWE and PEM hydrogen production systems are mainly introduced. Combining the current technology and market status of water electrolysis system, and referring to the progress of its test &amp; evaluation methods, this study analyzed the test &amp; evaluation methods of the whole product chains from material, single cell, stack, balance of plant (BOP) to the system levels. At the same time, referring to the progresses in the test &amp; evaluation methods, relevant suggestions are given for the establishment of test specifications and standards of water electrolysis hydrogen production system in emerging technology countries. The present study is significant to the improvement of water electrolysis technology and the standardized development.</div></div>
