TLDR
In this paper, the impact of cyclic compression on the Gas Diffusion Layer (GDL) has been investigated and it is shown that cyclic compressive compression causes significant and irreversible changes to the structure and properties of the GDL such as surface morphology, surface roughness, pore size, void fraction, thickness, electrical resistance, contact angle, water uptake and in-plane permeability.About:

A review of the gas diffusion layer in proton exchange membrane fuel cells: Durability and degradation
TL;DR: In this article, the degradation of the gas diffusion layer can be divided into mechanical degradation, including the compression force effect, freeze/thaw cycle effect, dissolution effect and erosion effect, and chemical degradation, which consists of the carbon corrosion effect.

Stainless steel as a bipolar plate material for solid polymer fuel cells
TL;DR: In this article, three stainless steel alloys, 310, 316 and 904L, have been evaluated in terms of the electrical resistance of their surface oxide film and showed that ohmic losses exhibited in fuel cell performance varied depending on the elemental composition of the stainless steel alloy.

The effects of compression and gas diffusion layers on the performance of a PEM fuel cell
TL;DR: In this paper, the performance of a PEM fuel cell is presented as a function of the compression pressure resulting from torque on the bolts that clamp the fuel cell, and an optimum bolt torque was observed when ELAT® or a combination of CARBEL® and TORAY™ gas diffusion media were used as diffusion layers.
