Study on Environmental Adaptability of Metal Plate Fuel Cell

As a main task of national key project (2018YFC081000)“emergency power under the special environment systems research and application demonstration”, Study on Environmental Adaptability of Metal Plate Fuel Cell.the paper focus on the key technologies needed to be developed of researching PEMFC system to adapt to the special environment of high temperature, high humidity, high salt, high cold and high altitude;this topic reviews the impact of plasma exchange membrane fuel cell and climate environment on such emergency power supply equipment, and uses Au@TiN as a metal bipolar plate of proton exchange membrane fuel cell. After a series of tests, it proves the excellent operation characteristics of the fuel cell reactor in “4-high” environment.the study showed that after constant 1.0 V (vs SHE) potential polarization, the size order of different coating corrosion currents is: gold plated> stainless steel> carbonization;In a high altitude environment, the optimal air intake parameters are obtained by numerical simulation and optimization of air pressure, air volume, wind speed, air excess coefficient and other parameters;In a high-temperature environment, the problem of the metal bipolar fuel cell supply system can be solved by improving the flow structure of the air side to increase the heat exchange area and the air capacity;In the high-cold environment, the shutdown pulse sweep scheme is adopted, and the rapid start of hydrogen battery supply system is realized by using hydrogen catalytic reaction assisted heating.
