Based on the energy conversation of proton exchange membrane fuel cell (PEMFC) stack, the nonlinear temperature model of PEMFC stack with the large range of disturbances is developed.

基于质子交换膜燃料电池电堆的能量守恒，建立了在大范围的负载扰动下电池电堆温度的非线性模型。

Comparing with hydrogen, reformed gas feeding to proton exchange membrane fuel cells (PEMFC) can avoid the inconvenience of the storage and transportation of H2, also expand PEMFC stack usage range.

与使用氢气为燃料气相比，以重整气作为质子交换膜燃料电池的燃料气可以避免氢气储存与运输的不便，更可以增加PEMFC的适用场合和范围。

Before July 4, 2012, the Higgs boson mass could only be in the 122 GeV to 130 GeV mass range (units where the proton mass is about 1 GeV, and the W and Z vector bosons are 80 GeV and 90 GeV, respectively).

However, the mid-range sedan's platform (underbody structure and chassis) is entirely Proton, a major step for the carmaker, whose other models are based on Mitsubishi or Citroen platforms.
