Embodiment 1

[0099] This embodiment provides a method for evaluating the performance of a fuel cell engine, the method comprising the following steps:

[0100] (S1) Determine the factors in the two-level evaluation index of fuel cell engine performance, such as figure 2 As shown, wherein the factor set U={U1, U2, U3, U4, U5, U6, U7}={power, economy, environmental adaptability, comfort, compactness, start-up performance of the first level index ,reliability};

[0101] The factor set U1={U11, U12, U13, U14}={rated power, peak power, 10%-50% PE response, 10%-90% PE response} of the second-level index of dynamic performance;

[0102] The factor set U2={U21, U22, U23, U24}={idling point efficiency, maximum efficiency, rated point efficiency, peak point efficiency} of the second level index of economic efficiency;

[0103] The factor set U3={U31, U32, U33}={the highest operating altitude, the highest operating temperature, the lowest starting temperature} of the second-level index of environm...

Abstract

The invention provides a fuel cell engine performance evaluation method, which adopts a fuzzy analytical hierarchy process to comprehensively evaluate each index of the performance of a fuel cell engine. According to the fuel cell engine performance evaluation method, the performance of the engine is evaluated through using at least two levels of indexes, the defects that an existing fuel cell engine system is one-sidedness and cannot be quantified are overcome, the problem that consistency detection of an analytic hierarchy process judgment matrix is complex and tedious is solved, the performance of the fuel cell engine is quantified, and evaluation is accurate and comprehensive.

Description

technical field [0001] The invention relates to the technical field of fuel cell engines, in particular to a method for evaluating the performance of fuel cell engines. Background technique [0002] Fuel cell electric vehicles are considered to be the ultimate development direction of new energy vehicles due to their long driving range, convenient fuel filling, and performance similar to traditional vehicles. In recent years, the field of vehicle fuel cells in my country has developed rapidly, especially in the integration and application of fuel cell engines, and a lot of practical experience has been accumulated. [0003] Among them, the vehicle fuel cell system is the most critical component of the fuel cell vehicle, and its performance determines the performance of the fuel cell vehicle to a large extent. Due to the complexity of the vehicle fuel cell system, the performance shown is very complicated. In fact, the overall performance of the vehicle fuel cell system doe...
