这篇文章指出,燃料电池具有改变能源产生方式的潜力,使其更环保、更高效。文章认为,燃料电池通过将化学性的能量直接转化为热能和电能的形式,产生了不需要的副产品。虽然燃料电池提供了相当大的利益,但仍有必要进一步研究和研究它,以使这些装置在质量和广泛使用方面发挥作用(Ludlow et al., 2006)。本文认为,低温质子交换膜(PEM)燃料电池是最常见的燃料电池类型之一。然而,这种燃料电池类型的主要问题是水的管理。正如燃料电池的名字所暗示的,PEMFC依赖于将质子作为电解质的细胞膜分离。

目前常用的膜是全氟磺酸基聚合物(PFSA),由类似于用磺酸(HSO3)去除特氟龙的主干和侧链组成(Ludlow et al., 2006)。通过膜的水化作用,确定了不同水分子量的氢离子,并对磺酸位点进行水化处理。本文采用实验和理论框架相结合的研究方法,对中子成像在燃料电池内部水管理中的应用进行了评价。使用实验方法进行数据分析,本文通过实验收集主要数据(Ludlow et al., 2006)。实验是用中子成像的方法在细胞上进行的,该细胞是由膜构成的,即GoreTM 5510。建立了燃料电池图像被脱水燃料电池图像所水化的图像分割,导致了在水的含量内指数的减法和基于变化的隔离。

It is suggested by the article that the fuel cells consist of the potential to change the manner in which the energy is generated to the more environment friendly and efficient manner. The article argues that the fuel cells present the by-products generation that is not desired through converting the energy of chemical nature directly to the thermal and electrical form of energies. It is essential to consider that although considerable benefit is offered by the fuel cells, there lies a need to further research and work upon it for bringing the devices in the mass and widespread utilization (Ludlow et al., 2006). As asserted by the article, low temperature proton exchange membrane (PEM) fuel cell is one of the most common fuel cells type. However, the prevailing issues within this fuel cell type is the management of water. As implied by the name of the fuel cells, PEMFC relies on separation of the membrane conducting the proton as an electrolyte.

The membrane that is usually used presently is the perfluorosulfonic acid based polymer (PFSA) consisting of the backbone and side chains similar to Teflon eliminating with the sites of sulfonic acid (HSO3) (Ludlow et al., 2006). Upon the hydration of the membrane, the hydrogen ions are identified to be solved with the different water molecule amounts and hydrate the sulfonic acid sites.This article employs a mixed research approach in which both the experiment and theoretical framework have been used in order to evaluation the neutron imaging application to the management of water within the fuel cells. The experimental method is used for the data analysis, and the article engages in the collection of the primary data through conducting the experimentation (Ludlow et al., 2006). The experiments were conducted with the approach of neutron imaging over the cell that was built with the membrane namely GoreTM 5510. It is established that the image’s division of the fuel cell that is hydrated by the dehydrated fuel cell image results in the exponent’s subtraction and change based isolation within the content of the water.
