Cymhwyso llwyth electronig perfformiad uchel mewn prawf polaredd gwrth-wrthdroi celloedd tanwydd

Fel dyfais trosi ynni glân ac effeithlon, defnyddir celloedd tanwydd yn eang mewn ynni, cludiant a diwydiannau eraill. Mae eu sefydlogrwydd, bywyd gwasanaeth a gwydnwch bob amser wedi bod yn ffocws sylw diwydiant. Mae polaredd gwrthdro, fel ffenomen sy'n achosi methiant pentwr celloedd tanwydd hydrogen, wedi dod yn un o ganolbwyntiau diwydiannau cysylltiedig yn raddol.

● Definition and hazards of reverse polarity

Reverse polarity is a phenomenon in which the output voltage of a fuel cell changes from positive to negative during operation. During the operation of the battery, when the fuel and oxidant are sufficient and effectively introduced into the battery, the electrochemical oxidation of the anode hydrogen fuel and the electrochemical reduction of the cathode oxygen will continue. However, factors such as start-stop, load change, operating errors and external environment can easily cause insufficient supply of anode fuel or cathode oxidant. When the gas shortage occurs, the working current of the battery will turn to drive the reverse polarity reaction in the anode or cathode, which will cause the battery output to become negative pressure.
The reverse polarity will generate huge heat, which is easy to cause pinholes in the proton membrane and cause a short circuit, which will cause irreversible attenuation of the fuel cell and even lead to catastrophic accidents. Therefore, anti-reverse polarity performance is the focus of fuel cell research and development, design, production and manufacturing.

● Datrysiad NGI

NGI has been deeply involved in hydrogen fuel cell testing for many years. The N62400 series of ultra-low voltage and high current electronic loads launched by NGI can be used for fuel cell reverse polarity testing. It supports up to -3V@2160A load, which can meet the characteristic test of the full range of operating voltage points of a single fuel cell.
