Endoreversible chemical pump (ECP) is a theoretical model of electrochemical, photochemical, solid-state apparatus and mass exchangers. ECP can be classified as two-, three- and four-mass-reservoir devices. The usual performance indicators for ECPs are energy pumping rate (EPR) and coefficient of performance (COP). Energy-based ecological function objective (EFO) is introduced to performance optimization of three-reservoir ECP. Optimization relationships between EFO and COP with linear and diffusive mass transfer laws (MTLs) are deduced. Numerical examples are provided, and influences of cycle parameters and MTLs on optimal EFO performances are analyzed. For linear MTL, compared performances at maximum EFO point and point where dimensionless EPR is 0.016, COP increases 14.4% and entropy generation rate (EGR) drops 52% with only 30% loss of EPR. For diffusive MTL, compared performances at maximum dimensionless EFO point and point where dimensionless EPR is 0.01, COP increases 11.3% and EGR drops 46.9% with only 30% loss of EPR. It demonstrates that EFO is a trade-off between EPR and dissipation of EPR, which is beneficial to utilize energy effectively. With the same chemical potentials of three reservoirs, the maximum dimensionless EFO and the corresponding COP with linear MTL are bigger than those with diffusive MTL.

三水库内可逆化学泵的最大生态功能性能

内可逆化学泵 (ECP) 是电化学、光化学、固态装置和质量交换器的理论模型。ECP 可分为两质量块、三质量块和四质量块储器装置。ECP 通常的性能指标是能量泵送速率 (EPR) 和性能系数 (COP)。将基于能量的生态功能目标（EFO）引入到三水库ECP的性能优化中。推导了 EFO 和 COP 与线性和扩散传质定律 (MTL) 之间的优化关系。提供了数值示例，并分析了循环参数和 MTL 对最佳 EFO 性能的影响。对于线性 MTL，比较最大 EFO 点和无量纲 EPR 为 0.016 的点的性能，COP 增加 14.4%，熵产生率 (EGR) 下降 52%，EPR 仅损失 30%。对于扩散式 MTL，比较最大无量纲 EFO 点和无量纲 EPR 为 0.01 的点的性能，COP 增加 11.3%，EGR 下降 46.9%，EPR 仅损失 30%。这表明 EFO 是 EPR 和 EPR 耗散之间的权衡，有利于有效利用能源。在三个储层的化学势相同的情况下，具有线性 MTL 的最大无量纲 EFO 和相应的 COP 大于具有扩散 MTL 的。
